7 Minute Workout Challenge for Android

7 Minute Workout Challenge offers a high-intensity program, made up of 12 bodyweight exercises of 30 seconds each with 10 second breaks between them that you can perform without any equipment for over an hour.

Pros

Wonderful design: 7 Minute Workout Challenge's beautiful interface, with videos and images seamlessly integrated into each exercise page, is a pleasure to look at. The exercise examples, in which you can view a male or female pro performing them in a short animated video, look stunning and teach you how to do each exercise correctly.

Gets you moving: With its clear purpose, wonderful workout animations and images, and callouts before and during exercises, this app works you into a sweat, helping you go through the 12 exercises, which include pushups, tricep dips on a chair, and planks, none of which are particularly easy.

Motivating achievements: As you practice, you unlock achievements that keep you going. If you exercise daily and attain achievements for weeks and months in a row of uninterrupted exercise, you can use them to unlock three premium exercise packs, so that you won't have to pay money for them.

Cons

Somewhat boring introduction: Rather than a wall of text that explains the origins of the 7 minute workout in the ACSM sports and health journal, the developers could have used a video or a slideshow to present the concept and the app.

Could provide more information about exercises: The app would be even better if it told us how many calories each exercise burns or what muscle group it trains.

Bottom Line

7 Minute Workout Challenge stands out as a great fitness app, one that's all about helping you get straight to business and do some awesome exercises.
