I've got a hand injury which prevents me from gripping very hard. (RSI
from typing too much.)
I can still work out my chest and my triceps, because, on a bench press
machine, you don't really have to grip the handles, you just push on
them.
I can't figure out how to work out my upper back or triceps. Pull-ups,
rows, bicep curls, and their machine equivalents all seem to entail
gripping a bar and then pulling it towards you. (That's just the nature
of the exercise.) I tried "weight lifting hooks" (basically, hooks
attached to straps that go around your wrist). They sort of worked for
pull-downs, but it was painful.
Got any suggestions?
