Melissa said:I'm trying to incorporate deadlifts into my routine, and I have a
technique question. Should my back "open" up at the same time as my
legs straighten or should I sequence the two parts, keeping my back at
a constant angle to vertical while I straighten my legs and then open
my back? What are the advantages/disadvantages of each? My tendency
seems to be to sequence the two parts, which I think is a fairly
ingrained movement pattern for me from rowing.
The problem with this pattern is that it tends to leave the
weight/lifter center of gravity very close to the edge of the base of
support - or even off it. So great stress is placed upon the lower back
to finish off the lift, which can lead to the back rounding and injury.
If moderate weights are used this isn't a huge issue. So if you are
training simply to look good and get hypertrophy in the right places it
probably isn't a problem, as long as you keep your back neutral or flat.
If you are training for strength or competition it can be a problem.
Ideally in a powerlifting deadlift, whether conventional or sumo style,
the bar and hips rise at the same rate and the bar stays in as tight to
the body as possible. Having said that, there have been some great
deadlifters who use a 'two-stage' technique - Vince Anello, John Kuc and
Lamar Gant all coming to mind immediately. In every case these lifters
have very short backs, which allows them to get away with this
technique. Most women have the opposite problem - relatively long torsos
as compared to limb length.
So two-stage technique is essentially doing a partial hack squat
followed by a stiff-legged deadlift. Fine for general purposes as long
as you are very careful to keep the lower back neutral or flat during th
elift. Not so good if the intent is to handle maximal or near maximal
weight.
You may want to switch to a sumo style lift, which can help change the
motor pattern developed by rowing.
