http://www.discussbodybuilding.com/(c) DiscussBodybuilding.com30 I notice when I do tricep pushdowns that my abs get engaged. Also, looking in the mirror at my form as I do reps, I tend to hunch over the V-bar, with shoulders forward&nbsp;as opposed to standing perfectly straight with shoulders back. Can someone clarify the correct posture? <br> &nbsp; <br> Also, when nearing failure on preacher curls (which I find comes very suddenly!), is it acceptable to 'cheat' in order to squeeze out another rep or two, or should I just keep my torso relaxed and once my arm stops working, accept defeat at that point? <br> &nbsp; <br> Cheers, <br> Ian. <br> http://www.discussbodybuilding.com/fb.ashx?m=196384Wed, 01 Nov 2006 11:42:27 GMT
