Intensity is a workout and fitness tool designed to assist you with both conditioning and strength training. It's suitable both for time based exercises such as interval training or circuits, and for reps based exercises such as those common in strength training programs. Being able to mix and match those two modes results in challenging, effective and fun workout programs! With Intensity, you can use the same tool for so different training regimens as stationary Tabata intervals and body weight circuits or running intervals, while keeping track of all the workouts in the same place.

Each workout you complete is added to your workout log, for you to revisit later to review your training or to find that great workout you did last week and want to do again.

With the "intensity control", you can adjust the difficulty of exercises by changing the duration or number of reps. This lets you increase the intensity as you get more and more fit, adding to the challenge.

Intensity comes with a number of sample workouts to get you started and inspired: 6 different circuits (including the 7 minute workout), 2 high intensity interval schemes including Tabata, 2 isometric workout programs, 2 pyramid workouts and 1 maintenance program. You can easily change those programs to fit you even better, or create your own workouts.

Disappointed. It doesn't work.

This looked like it would fit my needs perfectly. I wanted to be able to track custom workouts. I haven't been able to try it out because every time I try to create a new workout, it crashes. Waste of $2.

This app was exactly what I was looking for! Pre programmed workouts with times and explanations. Very simple and easy to use. I emailed support with a question and they got back to me in the same day with a great answer. I would recommend this app to anyone looking for a quick effective workout.
