Trap training using the lunge machine. This is great as the machine has each arm lifting separately. I train traps with Shoulders but am careful to focus more on the medial head of the deltoids and not as much on traps. I do them every other shoulder day because my traps grow easy and when traps are too big they make your body look like you have slope shoulders. Still traps should be trained with any type of shrug. 3-4 sets of 10-12 #traps | Rich Gaspari
