After recently attending strength training workshops put together by the SRU (scottish rugby union), hear is how i best describe u performa deadlift.
1.Crouch down to the bar feet shoulder width.
2.Ur feet should go under the bar, if ur wearing trainers, the bar should be roughly over the bottom lace hole.
3. The grip u take on the bar is more of a personal preference to urself.
4. After gripping the bar u should be leaning over the bar sum wat.chest up and out, shoulders back,back flat.
5. the 1st portion of the lift is done with legs, to emphasie this imagine placing a broom stick on ur upper back (it will be at almost 45degree angle), as u press up with legs the broom stick should not change angles.
6. As ur legs are approaching a straight position u straighten up ur upper body.
of course this isnt always to do, but those are what iv tried to go with. Trying to straighten up ur upper body straight away b4 u have any momentum comeing from ur legs, or before ur are more than 1/2 way thru the lift, will put too much pressure on the lower back and will lead to injury.
