How to make non-dominant arm keep up with the other
Started working out 6 weeks ago. Btw, I have thoracic scoliosis and it's on 20-23 degrees rn which is considered mild. My orthopedic said I need to start to be physically active. I'm 30, ectomorph, 5'3 and 61kg. I want to bulk and look thick because I've been skinny my entire life..
I hired a personal trainer but I'm not really satisfied. Right now, I'm just learning a the proper forms for workouts. I told my PT my scoliosis and I don't think he keeps it in mind that I have it because I've researched and some of the exercises and stretches he gives me are bad for people with my problem.. I'll just avoid them once im done with my sessions.
Anyway, my main issue right now is my left arm. I've seen that it's normal for the non-dominant arm to struggle and I need to adjust my reps based on how much maximum rep my left arm can take with my right arm..
Can anyone give me tips on how to improve on this? Also, I've read that it takes months.. that's fine as long as it's not years..
