I meant tricep pushdown.
I can't do any type of squat, I can do leg presses as long as the maching isn't on a incline which unfortunitly the gym i go to, its machine is on a incline.
I am not sure if my gym has a row machine I will have to check.

does doing back excerises before biceps really matter?(I am curious not trying to be a smartass). I thought skullcrushers worked out your triceps more then chest, why should I move it to my bench day?
Also is 5 sets of 10 over working the muscles? Is that why you suggest 5 x 5 instead?
