1. Get comfortable kicking up into a handstand against a wall. 2 weeks
2. Hold the handstand for time building up to 1-2 minutes. 4 weeks.
3. Do 5-7 sets of handstand holds of 30s-1min. Rest a couple minutes between sets and stop once you have accumulated 3-5 minutes. 2 weeks.
4. GTG on partial handstand push ups (put something soft under you in case you biff it) Do multiple sets of 5 reps through out the day on your rest days. Increase ROM as you feel fit until you reach a full handstand pushup. 1-3 months. (depending on how big of a guy you are).
