Exercise: most of us hate it and wish we did it more often. The key? Finding a routine that doesn't take too long but also doesn't try to pack two hours of work into four minutes, leaving you feel like you're lucky to be alive. Over the last couple of years, tons of of quick exercise routines you can actually stick to have surfaced. Pick one and get started this weekend.

Simple Circuit Training

Circuit training workouts are great because you can pick a few key exercises for the day and just keep doing them for 20 minutes (or until you can't go on anymore). The downside, of course, is that these workouts tend to be a little difficult in the beginning but if you stick with them and don't expect too much of yourself right off the bat, you'll get in better shape with a small time commitment.

Our guide to getting a complete workout with nothing but your body features plenty of simple exercises you can start with. Just pick three to five that focus on different parts of your body and swap them out with other routines during the week. You can also spend different days concentrating on specific parts of your body (e.g. arms, legs, or core) when you want more focus but try to work in some sort of cardio whenever possible. For some assistance, check out previously-mentioned mobile and webapp Sworkit. It creates randomly-generated circuit training workouts, walks you through them, and tracks your progress. The app is free to use, but a pro version offers additional features.

Tolerable Interval Training

Interval training proves that you only need about 20 minutes worth of exercise per day to get in shape. Like circuit training, interval training tends to require harder work for a shorter amount of time but it can be a lot easier than you might think.

Researchers found that the single most effective exercise regimen may be spending 20 minutes on a stationary bike performing micro intervals. You simply pedal slowly for 12 seconds, pedal as fast as you can for 8, and then repeat this process 60 times (for a total of 20 minutes). The exercise itself isn't that hard, but it requires a lot of attention. Thinking about exercising for 20 minutes can feel like torture even when it isn't. To help solve that problem, I developed an app to keep you on track with this specific flavor of interval training. That way you can watch TV, listen to a podcast, or engage in a variety of other activities and only sort of pay attention to the fact that you're working pretty hard.

A Comprehensive Micro Routine

A full body workout doesn't require a gym or much time at all. In fact, you can manage on in just seven minutes. The American College of Sports Medicine's Health and Fitness Journal highlighted an effective, quick routine that uses your body weight to provide a comprehensive work out and help you get you in better shape. Like the bike interval training method mentioned about, this routine was essentially developed in a lab to find a simple and quick way for people to exercise on a tight time budget. If you're in a rush, this is the routine for you.

Don't Forget About Your Diet

Exercise is only one piece of the puzzle. A healthy diet matters just as much. Different diets work better for different people, so you'll have to find the right one for you, but you should be able to make a significant impact by simply limiting your portion size to only what you need and making healthy substitutions for unhealthy foods. Whatever you do, don't expect exercise to turn you into a Greek sculpture. Diet matters, too, so don't make it an afterthought!

Good luck, and happy Friday everyone!

At some point you've been told to fake it 'til you make it, and that's because with a little effort you can delude yourself into believing—and then becoming—whatever you hope to be. As A.J. Jacobs, author of Drop Dead Healthy, points out in this quote, we're a lot more flexible and less stubborn than we may think. He explains:

Our behavior greatly affects our thoughts and attitudes. If you are feeling a lack of confidence or have an urge to change something within yourself, you must “act your way into a new way of thinking,” rather than trying to think your way into a new way of acting.

Not sure how to fake-act? A few body language changes can make a big difference.

Cooking at home can save you a lot of money, but you can also rack up a huge grocery bill learning to make certain dishes that don't always turn out better than their cheaper counterparts. What are your favorite inexpensive, home-cooked meals?

Personal finance blog Wise Bread shares a number of recipes that cost as little as $2 each to make. That seems a little on the excessively cheap side, however one of my favorite cheap meals—which comes out to about $2—is just rice, beans, and veggies. What's yours? Share a recipe if you've got it!

Google didn't announce the latest version of Android at I/O, their annual developer conference, leaving our devices feeling sad and unloved. Android 4.3 may still be on the way soon, but for now, here's what we wish they announced—and how you can get many of these features right now.

A Smarter Lock Screen

Android's lock screen has evolved in many ways to include widgets and a Google Now shortcut, but it could use a bit more. We've wanted more shortcuts to our most-used apps, notifications, and extensions to add even more. Fortunately, a few apps can give you those features right now.

Dashclock (Free) supercharges your lock screen, and we've got a great guide to help you set it up. Not only does it look great, but it'll provide notification via icons and/or text, useful information like weather and appointments, provide audio controls, and a lot more. Most importantly, you can extend Dashclock to do a number of things to make your lock screen incredibly useful.

For those who prefer a more iOS-like interface, try LockerPro ($4). Due to its higher price and fewer useful features it comes hard to recommend in comparison to Dashclock, but some may prefer its interface if they like the way iOS handles its lock screen.

If you want quick settings to your favorite apps, you can grab something like WidgetLocker or flash a ROM like CyanogenMod, which give you a more dynamic lock screen. Not only will you get your favorite widgets, but you can add buttons to your most used apps for quick access—no swipe-to-unlock required.

Profiles for Settings

Android does a great job of taking care of things for you so you don't have to waste your time doing them yourself. One great example that just got a little bit greater? Google Now. But Android doesn't manage your settings based on your location or needs right out of the box. When our sister site Gizmodo went through the 15 features they want from Android, this was one they mentioned, and we agree: the ability to create setting profiles and switch between them easily. Custom ROM Cyanogenmod adds this feature, but if it doesn't support your phone you'll want to check out Setting Profiles ($4, Lite).

Setting Profiles allows you to automatically activate different settings on your phone based on your location, battery condition, and other rules. For example, when your battery gets low you could have a profile that automatically disables power-hungry features like LTE, GPS, and high screen brightness.

A Unified Messaging System

Google Voice provides anyone with the ability to send/receive text messages and receive calls from their Android phone or computer. It's a really great service, but it has yet to see a significant update in quite a long time. Meanwhile, Apple's iOS offers a nice unified messaging system in the form of iMessage. While both have their faults, it would be nice to see Android take Google Voice a step further and support picture messaging and group messaging (MMS)—at the very least.

If you want an alternative to Google Voice that offers these additional features, try MightyText. It provides access to your text messages on any computer, via a web interface, and on tablets as well. This way you can not only keep all your messages in sync, but also receive MMS on every device. Future versions of MightyText will include photo sync, too, so you'll get new features as development progresses.

Simpler App Management

Installing apps through Google Play works great, and organizing your home screen doesn't take much effort either. When you want to remove an app, however, you can uninstall it from your home screen—you can only remove it. We'd like to see simpler app management with options. Custom launchers, such as NOVA Launcher, allow you to press and hold apps and decide whether you want to remove them from your home screen or uninstall them from your phone. You also get quick access to app info pages so you can clear their caches and manage their other settings with ease.

Alternative launchers provide a number of other great features that enhance your home screen's abilities and its interface, so we highly recommend installing an alternative to the default if you haven't already.

Also, check out Andmade Share if all of this isn't enough. It'll allow you to reorganize Android's share menu and prioritize the apps you use most.

Other Features Google Needs to Improve

Unfortunately we can't add every feature and fix we'd like to see in the next version of Android. Here are the major items on our wish list:

• A consistent back button: Android's back button doesn't always work quite the same way in every app, so it takes a little trial and error before you know where you're going. We'd like to see Google set some guidelines for how the back button should be used so users always know what to expect.
• Clean up the notifications drawer: While we've always loved Android's notification drawer, we'd like to see a little more organization. Even something as minor as notification categories or organization by app would make a big difference.
• More resizable widgets: We like the ability to resize widgets, but some can't be resized at all. Custom launchers help a little bit in some cases, but not in all. Additionally, sometimes certain sizes of widgets leaves them feeling unevenly spaced on your home screen. We'd like to see a few updates to make everything fit better and look nicer.
• Social media integration in the notifications drawer: iOS offers the ability to tweet and post to Facebook from its Notification Center, so why shouldn't Android? Also, if Google made notification drawer widgets an option we could do much more (like check weather or search the web).

All of this said, Google made Android pretty amazing since 4.1 and a lot of the features we want we can wait for. But part of what makes new versions of Android great is that we get a bunch of cool features we couldn't have thought of ourselves. With Android 4.3 rumored for June 10th, we may see a decent update. Hopefully it'll bring some excitement many felt was missing from this year's I/O keynote.

We all intend to remember to put our laundry in the drier, but sometimes life gets in the way and we return to a stinky clump of clothing that often smells stale even after you dry them. Instead, DIY Life suggests a half cup of white vinegar will do the trick:

Many people already know that white vinegar in a small bowl will remove smoky or musty odors, and that you can put the bowl on a closet floor or shelf if those odors happen to be stuck in your coats and jackets. What many people do not know is that, if you put white vinegar in your wash water at the beginning of a laundry load, it will both freshen and soften the clothes being washed. The scent of vinegar will have miraculously disappeared by the end of the wash cycle, but everything will smell very clean. You don't need much vinegar: a half cup is sufficient, a full cup is plenty, and exact measurements probably aren't necessary. Don't forget to add your usual detergent, too!

You don't need to run the wash for quite as long the second time. Make it short and sweet and say goodbye to that stale smell.

Google broadcast the I/O 2013 keynote live on YouTube today, giving a detailed peek into the latest updates to their various technologies across Android, Chrome, and the web as a whole. The I/O conference consists of a lot more than announcements, however, with displays showing off all kinds of technologies Google and third parties employ to make the web and mobile devices better.

We registered on Tuesday to ensure we didn't run into any delays when getting to the keynote the next morning. Registration was super simple. You just checked yourself in with a QR code or confirmation number on a Chromebook and proceeded to the appropriate table to pick up your NFC-enabled badge. If you had an NFC-enabled Android phone, you could just tap it to the badge to get a variety of information. It also included personal data for I/O conference workers to confirm your identity.

Whitson and I had a surprise visit from Pash at our hotel, who brought along his Google Glass. It's very interesting to watch someone use it because they're having a very specific experience, seeing something only they can see. It looks like they're rubbing their glasses but they're actually navigating an interface. When Glass talks to you, it uses the bones in your head to amplify the sound so it tickles a little when making noise.

We woke up at 6:00 AM to get ready for the keynote and headed to the Moscone Center around 7:00 AM. From there we got to hang out in a press room and eat pastries while we waited for Google to escort us to the keynote room. After that, we waited outside the doors for a bit then went into the press area up front. It was a great view, and we were surrounding by some of the most enthusiastic developers I've ever met. People came from all over the world. It was really neat to see different development teams from so many different cultures.

Despite Google's advanced technology, they still can't get Wi-Fi to work well in the Moscone main room. I was able to get a hotspot running on my Nexus 4, but Whitson and I couldn't use it at the same time. He needed to relay instructions to the other writers so he used the connection and I made due with the Wi-Fi when it worked. It gave me a chance to enjoy the keynote a bit more and take lots of pictures.

Google announced a lot of little things during the keynote, but Google Maps provided some of the best imagery.

Larry Page came out to talk in front of one of the most stunning images.

For the first time, he answered questions live during the keynote. Naturally, Robert Scoble was first in line.

Two young people made it to the front of the question line. Google seems to be sponsoring a lot of young, intelligent developers. It's great and almost intimidating how smart kids are now.

Also, this Jon Hamm look-alike.

After the three-and-a-half hour keynote, we were all very hungry. Fortunately Google had lots of good food and excellent cupcakes.

Beyond the keynote (and lunch) there were lots of awesome booths and displays. Everywhere you looked, you could find plenty of Android guys—including these flying ones.

A big roundtable let people try out and learn about Google Glass.

I'm not entirely sure what this Chromebook Pixel display was supposed to do, but it was interesting to watch.

The Chrome display had all sorts of Chrome web app demos and developer resources.

Then there was the photosphere, which displayed—you guessed it—photospheres!

Inside you could watch different photospheres from various locations around the world.

We were told to expect some Google TV updates but didn't really find any. It just seems a few new TVs are running the latest version we already knew about. No surprises here.

Although mostly just for display, this Google Voice Search Phonebooth was pretty awesome.

There were tons of other cool booths. This one was really fun to look at.

There were so many other things to see at I/O—too many to show them all. This Google Maps hiking bot was pretty amazing, though. They let people strap it on and see what it's like to map out a hiking trail for Google Maps.

Lastly, this motion-tracking flying game was a lot of fun and reminded me of Pilotwings.

Beyond the booths were tons of sessions on the future of Android, Chrome, and the web. While not as outwardly exciting as the sorts of announcements that come out of I/O each year, some very cool technologies are coming that will make mobile devices and web apps significantly better. By 2014, the web, especially, should change for the better in some pretty amazing ways. If nothing really excited you at I/O's keynote today, stay tuned—some really great stuff is coming not necessarily from Google but the developers they help to create great things.

OS X loves to devote resources to the user interface to fill your world with drop shadows and animations everywhere you go. That's fine on a powerful, newer Mac, but if you want to speed up an old one you need just one terminal command.

To disable superfluous window animations, just enter the following command in the Terminal:

defaults write NSGlobalDomain NSAutomaticWindowAnimationsEnabled -bool false

In the event you decided you want to undo this, just change the false at the end of the statement to true instead.

Android: Do you ever need to split a bill with friends at a restaurant but struggle through the math? Grouptuity helps you figure out exactly how much everyone owes, including tax, tip, and any discounts you may have, without too much hassle.

Tell Grouptuity who's eating, what they ordered, and if there are any discounts. It'll keep track of it all and split the bill with the exact tax and tip owed for each person. If anyone in the party shares a dish, you can assign it to both and they'll each pay half. Grouptuity is free to use for the most part, but requires three credits to see the final split bill with full calculations. You get 25 credits when you download the app, providing eight split bills for free. After that you have to pay $1 for an additional 100 credits. We find this a little irritating and would rather pay a few bucks for the app outright, but are glad you get to try it out for free. Definitely give it a look if you ever have trouble splitting bills with large parties. You can test it out eight times before you decide if you want to pay.

For those of you with iPhones who want a similar feature set, check out Billr instead.

If you want a loaf of sweet bread or a cake, starting with ice cream can save you a lot of time. Because ice cream contains many of the ingredients you need for these recipes—sugar, eggs, and fat—you can save yourself some time with just a few scoops.

All you really have to do is melt the ice cream, add flour, baking powder, and salt, and bake at about 350 degrees. When finished, you have bread! I've also heard that melted ice cream works as a substitute for the liquids you need for cake mixes and produces a more rich and moist cake. Check out the recipe at the Hungry Housewife for bread, and the post at WonderHowTo for additional possibilities.

Dear Lifehacker,
I want to eat a healthy, balanced diet, but does that actually include a multivitamin? If I eat well, shouldn't I get the nutrients I need by default? I assume a multivitamin won't hurt me, but I don't want to bother if it isn't necessary. Should I take a daily multivitamin or not?

Sincerely,
Vexed by Vitamins

Dear Vexed,
We all want a simple diet, but unfortunately those two things rarely match up. Although multivitamins can provide health benefits, they can cause problems as well. Ultimately you should speak with your doctor or a registered dietician about any significant health choices you make, but we spoke to Dr. Carly Stewart, medical expert at Money Crashers, to get some general advice.

The Pros and Cons of Multivitamins

According to Dr. Stewart, multivitamins offer a number of health benefits:

Multivitamins give people sufficient amounts of both vitamins and minerals that their current diet may not be providing. They can improve many bodily functions and assist with mental health. They can also help decrease stress.

That said, taking them can make us a little less diligent:

Taking multivitamins can cause people to pay less attention to their diets. Every effort should be made to get as many vitamins and minerals out of actual foods as possible.

Dr. Stewart notes that multivitamins cause the largest problem when they provide too much of something we don't need:

One of the biggest risks of taking multivitamins is that you may be ingesting too much of a particular vitamin, depending upon what your diet consists of. Some vitamins, if taken at a high level, will simply pass through the body without any negative effects. But both Vitamins A and D, which are fat soluble, build up in the body's tissue if too much is taken. Taking too much Vitamin A can increase the risk of osteoporosis, and taking too much Vitamin D can damage both the kidneys and blood vessels.

As previously suggested, we recommend discussing any important health choice with your doctor. You want to avoid taking vitamins you don't need and causing severe issues. It's also important to monitor and understand what you eat so you know when you're ingesting too much of a particular vitamin. Keep yourself informed and you'll stay safe.

How to Choose a Multivitamin

If you choose to take a multivitamin, how do you pick the right one? Dr. Stewart offers a few guidelines:

Consumers should stay away from multivitamins that contain more than 100% of any daily recommended dosages, as that can cause vitamin toxicity. Most multivitamins are geared towards either men, women, or even the elderly. Consumers should choose a multivitamin based on their age and sex. For those who have difficulty swallowing large pills, gel-coated capsules and liquid vitamins are also available.

You'll also see food-based vitamins offered on some shelfs, but for a much higher price. Marketing arounds these types of vitamins claim they offer better absorption and aid in digestion, but we currently don't know enough to validate those claims. Dr. Stewart explains one advantage:

Food-based multivitamins contain powdered fruits, vegetables, and other food ingredients, something that traditional multivitamins don't have. Taking food-based multivitamins can decrease the risk of an upset stomach and can generally be taken on an empty stomach without issue.

Whether or not that's worth the higher cost is up to you. Either way, you'll want to consider your specific situation when choosing a vitamin as well. For example, prenatal vitamins exist for pregnant women to provide additional nutrients they made need. Dr. Stewart explains:

The type of multivitamin does matter, depending upon your personal situation. Women who are or looking to become pregnant should take a multivitamin high in folic acid and iron, which can help prevent birth defects. Women in general should consider a multivitamin with Vitamin D and calcium, which can stave off osteoporosis. Most seniors need a multivitamin with higher levels of Vitamin D, which improves bone strength.

Ideally we'd all have a multivitamin tailored to our specific needs. While personalized vitamin services exist, they require frequent testing and monitoring and therefore cost a lot of money (and are so rare that few people have local access). While a one-size-fits-all option may help a lot of people in most cases, visit your doctor and discuss what you need before you make your decision. Plenty of variety now exists, and you can get individual vitamins if you don't mind swallowing multiple pills and wish to essentially create your own mix. Pick what suits you best based on your doctor's recommendations and it'll help provide what you're missing.

Love,
Lifehacker

Unless you have a dedicated laundry room in your house, you're familiar with dragging a huge laundry hamper down to the room in your apartment complex or laundromat. That trip becomes much less comfortable when you have to carry a large bottle of detergent as well. Laundry Dropps remove that hassle by providing pre-measured packs for easy traveling.

Laundry Dropps come in little plastic pouches that dissolve in the wash and release detergent as they do. When you're headed to the laundromat, you can just toss one in with you clothes and just dump it all in when you get there (presuming you don't have to sort first). Dropps are enzyme- and phosphate-free, so if you have sensitive skin (or are a baby) you won't have issues with the detergent. If you prefer a lack of dye, however, you can get Dropps without either of those things. They also offer fabric softener.

While Laundry Dropps seek to solve a primarily first world problem, they are one more tool to speed up and improve the world's most boring chore (here are some other suggestions). They don't really cost more per load than standard name-brand detergent, so you might as well make your life easier.

Bluetooth audio in your car makes it easy to push music from your phone to your car's stereo system, but you lose out on those benefits when you still have to plug in to charge. Reader and DIYer Ryan Wold solved this problem by installing an inductive charger inside his vehicle.

Ryan didn't have Bluetooth in his car already, so he needed to purchase an adapter. The problem with most adapters, however, is that they require you to press a button to connect each time. When you want to mount your adapter under a dashboard, you can't exactly push that button. Thanks to the HomeSpot NFC-enabled Bluetooth Receiver, Ryan was able to hide it under his dash and just tap his phone on the surface to connect. On top of that, he wired an NFC charger into his car to allow wireless charging as well. The entire setup doesn't see too difficult to pull off, costs very little, and appears completely integrated with his car. If you want to try this yourself, check out his video above for instructions.
