DL- sit your ass down. keep your head up. start the pull lifting with legs and back simletaneously(sp). keep abs tight, if wearing a belt push against it. PULL THAT ****ER UP YOUR LEGS! (most imortant thing IMO, it will keep form good). Once you get it up over your knees, shoot your hips through and lock it out.
Bench- mine sucks!, but this is what helps it not suck as much.... set up- get your feet planted. get an arch. push your upper back into the bench. unrack the weight and keep everything tight. grip the **** out of the bar and try to "pull the bar apart" to activate back. drive your heels into te ground, it will activate all the stableizers and get leg drive going. think of pushing yourself into the bench (really pushing the bar up).
I <3 front squats
