I love the fitness22 running programs and the push up 0-100 one. I was expecting this to be like the pushups one with 3 levels (such as counter, knee, reg push ups) but instead this one jumps right into doing pullups. I will find another one that helps build strength. Maybe men just can jump in and do pullups, but I am a female. I have made a lot of progress on the pushups app. I would recommend that app, but not this one. Update 10/29/16: I have gone back to this app as I have progressed to an assisted type pull up. It works well for me now (i use 35 lbs assistance). The picture it shows also shows a chin up in the instructions, not a pullup. I now recommend you start this with an assisted type pull up and go from there
