Animus: bw is 60-63% of bench - can do 10 freestanding
Con@n: bw is 63.9% of bench - can do 4 freestanding
jsmiley07: bw is 50% of bench - can do 5-10 freestanding?
I think this is interesting.
In order to do handstandpushups your bw needs to be 50-64% of your bench.
At 280lbs I would need a raw bench of 440-560 --- this is a ridiculous figure.
If I lost weight down to 220 I would need a bench of 343-440. The lower range here is just about achievable, but I doubt if my long arms will ever let me get there (and my bw will never be lower than 220 at 6foot9tall).
