second firehawk's setup. flat-back bodybuilder style only got me so far - once i switched over to powerlifting style, improvement was immediate and pretty steady.
using flatback, i maxed out at 120 - i could only do three, then stalled on the fourth rep. after something like three months using powerlifting style, i'm at 155 - still stalling on the fourth unless i have a spotter to hand off.
that's the other thing: MAKE SURE you have someone to hand off to you - otherwise your shoulders come untucked and you lose the form.
as a commentary to the video:
- keep your abs TIGHT
- keep your shoulderblades tight together to form a stable shelf
- don't stick your elbows straight out to the sides - keep them in at about 45 degrees
- the bar travels from your sternum (lower ribcage) to up over your chin
- drive down with your heels
- suck in a BIG breath at the beginning of the rep and hold it until you've got the bar back up. if you exhale halfway through, you lose leverage.
