Wowza! Good work! I did 15 after reading that, then noticed a weird wooshing in my right ear and stopped. But I definitely was not going to make it to 61! Then I realized that I don't think I used to be able to do even 10 regular push ups! But clearly I still have work to do.

You got me there! I've never tried to max jump onto box. My chin would probably end up spitting blood like a sprinkler
