Home workouts are great for a number of reasons: you don’t need a gym membership, you can work out in private and there’s no commute time. Add to that the fact that you can get a great workout in less than half an hour, and you’re basically left with no excuses. Here are a few of our favorite equipment-free workout tools.

I know what you’re thinking, and no, that’s not the off-brand Magic Bullet. FitnessBlender is a free video-based workout system, complete with a calendar, progress tracker and member forums. You can go through targeted programs (weight loss, abs, low impact, etc.) that take a few weeks each, and can search for workouts based on difficulty, length, focus and type. You can also save your favorite workouts.

7 Minute Workout App
The 7 Minute Workout App is just that: a full-body workout in seven minutes, guided by onscreen illustrations and a timer. Breaks are built in, and there’s a whistle noise to let you know to transition to the next exercise. The webapp works on mobile devices as well as regular browsers.

Popsugar’s FitFinder is a workout video search engine that lets you find workouts by fitness level, length, target areas, type and amount of equipment. Select what you’re interested in and Popsugar will give you a random workout that meets your qualifications. This tool is targeted at women, but could work for guys as well.
