Talking to a professional will definitely help, but a lot of people use a standardised program. For example I do this 2-3 times a week.
Warm-Up (1-3 mins rest between)
10 seconds on the big BM1000 edges, toes on ground
10 seconds on the big BM1000 edges, hang.
10 seconds on the 20mm edges, toes on ground
3x 10 seconds on the 20mm edges, hang
10 seconds, 20mm, 8kgs added
10 seconds, 20mm, 16kgs added
10 seconds, 20mm, 26kgs added
Main hangs
6x hangs at 35 to 40kgs added on the 20mm. 5-7 mins rest between.
Something like that would do you a lot of good. Of course work to your level and start by taking it easy, slowly build up. Max hangs after a few weeks of two sessions a week. Maybe you work up to adding 10kgs, or 15. And as always... don't hang, pull!
