A bench of over 400 is just inconceivable to me. Don't get me wrong, I've seen 'em. I just always benched roughly 10% more than my ancient italian granny did.
But deadlifts... I found when my squats stalled at somewhere around 400, deadlifts are what got them moving again. Evidently my back was the limiting factor in my squats, not my legs. Or... maybe it was about hamstring recruitment (hip extension), I'm not sure. But it felt like my back. Got my deadlifts up and went back to squatting, without having done a single squat in maybe 4 or 5 months, and beat my 1 RM my first attempt.
Deadlifts rule.
My grip sucks when I let them go, too. I think straps have their place, btw, but yes, it's good to work your grip.
I never used a belt, but.... I think based on myth, originally. and now habit. and simply not owning one. But I don't think they're in any bad, just often not used correctly.
Straps any day. I'm there to train my back, etc. not my grip. I can do other things to train for grip. My grip will give out long b4 my back will, what then? I wont get those extra 5-10 reps or so, then what's the point?
Many commercial gyms, like the one I am currently a member of, do not allow chalk and straps must be used. Straps are a good tool if you are forced to train in a chalk free gym. In my home gym I have chalk and therefore do not use straps. I find when you use chalk and a reverse grip holding on to the weight is not even an issue. I have been involved with powerlifting for years and have yet to see a lifter miss a deadlift because his grip was weak (assuming chalk and a reverse grip are used). I think the problem is with the guys who start a deadlift workout with a cinched belt and straps. However, most guys who train this way don't do deadlifts anyhow. You are far more likely to see these guys on a hammer strength machine or doing 65 pound cheat curls in the rack.
Build strong arms, jeremy? I'll save the arm training for arm day. Grippers among other exercises will do just fine for building grip/foream strenth and size. I deadlift just under 600lbs for a full range...which in return gave me one hell of a thick, well developed back. If i cut the sets short or lightend the load due to no straps, I wouldn't have achieved either. More sets you ask? Sounds like over-training to me.
