Right, when i train my chest it doesnt feel like i've trained it when i've done, neither does it ache the next day, basically i think the problem is with my arm's, i do 4 set's 1@12 reps 1@10 reps 1@8 reps and the final set to failure, i increase the weight slightly each set. when i try putting the weight up i can get the bar off my chest upto mid press no problem, its when my tri's have to start working to extend my arms that i fail, could this be why my chest isnt getting worked hard enough? is it possible to do like a half press so i'm just using mainly my chest? could it be technique? how far up my chest should the bar be? any ideas/tips/help would be great
