When doing movements like single arm preacher curl or bulgarian split squat, I can do more reps with one arm and 1 leg. In the program I should train to failure. Should I then start with weaker arm/leg and match the reps with stronger or also push the stronger to failure even if that means doing more work with that side. My logic says I should match the reps with stronger because the other option would not resolve the problem(if that is to be called problem). I just want to hear your thoughts on that. thanks in the advance for the reply.
