Quick and straightforward.

I have the pull ups and push-ups apps. They are easy and keeps me from having to any counting of remembering. Just start the app and go. My only question is to why the rest time is 1 min but clearly in the screen caps it shows 2 min. The push-ups rest is 2 min and pull ups are way harder exercise. A 2 min rest would be nice. I guess I can just make myself rest for 2 min though.
