1) I am in a similar situation I bought the perfect ab straps. I means I am not hanging but with straight arms but it keeps my feet off the floor.
2) I am on a hyprid program now but it is based on the one where I do two exercises. I started at step one for most things and as just moved on the next day. Pushups and Pullups I started on full because that is where I was.

Day 2 uneven chinups, pistol squats and deadlifts,
Day 3 handstand pushups kb press
