In reply to beardy mike:
I'd bought and never used finger boards in the past. It was only really the Beastmaker app that gave me enough discipline to to useful work. It's not easy work but if you stick at it you'll get there. The routines are based on 18 sets of 6 hangs (each hang 7sec on 3sec off) on diffrent holds. Typically there are 2.5min rest between each set and 6min between sets 6 & 7 and sets 12 & 13. Maybe first session just do sets 1-6. Like I said earlier the small crimps are nails so I let the timer run down to 5sec to go before starting rather than doing the full 7sec. I can do 5sec right through but if I try 7sec I crack after about 3. The slopers are very "conditions" dependent. Some days I can do all the sloper hangs, other times it is impossible. I started at the beginning with struggling on "5A" and progress to "6A" over about six months (I'm old). I skipped 5C as that seemed more brutal than 6A. Takes about 1hr 15 to get through all 18 sets. A warm-up that works for me is...
10min rubber ring squeezes, 10 LH, 10 RH, 20 LH, 20 RH, 30 LH, etc up to 60 then back down to 10.
20min pull-ups and press-ups... 5 pull-ups on the odd minute and 5 press-ups on the even minute.
I was doing it once a week for about 9 months (last year) but I dropped it to make time for other things. Expect to restart shortly once I chuck the Track Cycling again and ramp the climbing back up.
