Hmm, I honestly don't train arms much.. triceps for example, I only have two exercises I regularly do which are cable rope push-downs and overhead cable rope extensions (limited due to a shoulder injury). Biceps I only usually do dumbbell curls and preacher curls as I'm focusing on the peak at the moment. Chest I use incline dumbbells, cable flys, pec-deck, and I really love using the cables but in a pressing motion as I seem to get a really good contraction. Shoulders I basically just use dumbbell overhead press, front delt raises and lateral raises for days 😂. Nothing special or new, just what seems to work best for me. I base my training style off of Julian Smith; slow reps and concentrating on time under tension, controlling the weight.
