Physics puzzle: chin-ups.
Suppose I weigh 200 pounds and can perform a set of 10 chin-ups. What weight of dumbell should you expect me to be able to curl 10 times?

Re: Physics puzzle: chin-ups.
people who are very thin can often do many chin-ups but not curl very much.

i have no idea. [/ QUOTE ] So why post? [ QUOTE ] this is more of a personal trainer question than a physics one. [/ QUOTE ] It is a physics problem with applications to other areas. While I might get better feedback by asking experienced physical trainers, this has applications to bar bets, too. If you see that someone can't quite curl 75 pounds, is it safe to bet that he can't do a 1-handed chin-up? |

Re: Physics puzzle: chin-ups.
Surprisingly different exercises. It depends on how strong your biceps are vs how strong your lats are.
I can do chinups till kingdom come, but I have no biceps and I can't curl worth a damn. |
