I recently started training with a friend of mine, and on the days that we do push force exercises he keeps telling that he doesn't feel satisfied from the workout. Now this was very strange to me because I saw him struggle to get those 5 reps on the dumbbell chest press and on the overhead press. One time time during one of our workouts, I decided to do some chest presses and shoulder presses using the machines. During that workout I noticed that my friend's right hand is way stronger than his left. I had him press 100 lbs on machine chest press (pin loading) and after 3 reps he simply could not go on. He told me the reason he stopped was only because of his left hand with his right hand he could have gone for a few more. Not believing him I asked him to try to do a couple of presses using only his right hand. Sure enough he was able to do 7 reps with 100lbs with his right hand only.
This was when I understood why he wasn't feeling satisfied with the workouts. We were working well below the weight required to give his right hand a struggle. With all that being said, I wonder: what I can tell him to do so that he will start feeling satisfied from his push workouts like he does from pull and leg days?
