The only liability In the upper body as a leftover from powerlifting (165 and 181 classes) would be the aching I get in the traps on longer rides. That achey feeling is debilitating to the ride but will go away with conditioning though painfully slow. Ibuprophen has been my friend on some rides.

Hillclimbs are a treat, no difficulties whatsoever....same with stiff headwinds though not as fun.
