Great app!

I like this app for a quick, effective workout. Pluses are it tells you how many reps to aim for, has a clock timing you for each exercise, and bases the workout on how many push-ups you can do which is a great indicator of your fitness level. I love to switch up my workout and this app is one of my faves!
