I've been doing p90x minus the leg workouts due to a knee injury (patella pain, that I'm about to start PT for) for a couple months.
It involves some basic dumbbell exercises, overhead presses, various curls, tricep extensions and of course tons of pushups/pullups.
I've had a problem with my left arm being weaker than my right. I can easily curl 30lbs in my right arm but only about 20 in my left. What I've been doing is lifting 20 in both and stopping when my left gives out and trying to push out a few more in the left with the assistance of my right hand. It hasn't had an immediate effect on the imbalance but I'm hoping that it will eventually even out.
Does this seem like the best approach? Any advice?
