Recently I started at a gym. Of course, this generated soreness in my muscles, but now it is better. I have a few questions though (the trainer did not have time to answer them).
I use mainly machines, and have discovered that when I'm using them my left arm is weaker than my right. How can this problem be fixed? Using less weight for the left arm on the machines? (The bench press machine has separate devices for left and right arm, it isn't like disc bar).
Also, I feel like I'm going to have a flu soon, should I train or wait?
