The best way to guage strength is to do tricep kickback on the stability ball, its very hard.. Not only you have to stabilize your whole body with one knee on the ball, you're also kicking back a heavy dumbell for a 1RM..
Idk I say pull ups . I have not seen many women even attempt them at my gym ! Assisted let alone unassisted ! I can do at least 8-10 unassisted . Not that impressive ! But I'm proud ! Lol
Fireman Fran!!!! If you don't know what it is go to YouTube and watch. This is the most brutal exercise! It looks simple but trust me most people can't even do a full set just using the bar!
