Hello Mr. Paul,
I have a question about isolation work. Even though I am a fairly young guy (24), I’ve had a few issues with my joints in the past (I had lyme disease a few years ago. Its healed and all, but my joints turned out a little achy). I am not trying to get medical advice out of you, I would like to know your opinion on the subject. Some people say, that when you’re doing isolated work on a muscle, you shouldn’t straighten out the joint. This is in part to keep the tension constant, but also because It may result in undue stress on the joint. However, this also takes out some of the range of motion. Do you think that having joint health as a priority, should people lock out the joints during isolated work?
