deadlifts

I think ghs09 wants to know what muscle is work more: lower back or hamstrings. Also probably wants to know if the style of deadlift differs from the other.
 
With conventional deadlifts, I tend to feel it more in my lower back, and the legs just as a whole. When doing straigh legged, it definitely isolates more in my hamstrings, and of course still works the lower back...always nice to mix up all the variations...

theleip, how long does it take to be a Certified Personal Trainer and is the pay good?

I'll jump in on this one.. It depends on what cert you want, and how much you already know. And the pay varies, especially from working in a gym to working for yourself.
 
True - I know two guys who have the same qualifications. They are both personally trainers and sports massage therapists; both work part time in a gym and also work for themselves the rest of the week.

Last year one of them made £17K and the other made £40K
 
my question is between which deadlift works lower back and hamstrings more? betwwen convetional and sumo because thats the two variations i use
 
Both work lower back well.

The conventional deadlift uses hamstrings as a stabilizer where as the sumo there is more synergist activity involved. In short if looking to work both, go with the sumo.

Don't mean to contradict you, Leigh, but there's really no difference in myography data in hip extensor groups between the two variations (take a look at Escamilla, et al "An electromyographic analysis of sumo and conventional style deadlifts" as well as Cholewicki, et al "Lumbar spine loads during the lifting of extremely heavy weights" and Escamilla, et. al "A three-dimensional biomechanical analysis of sumo and conventional style deadlifts")...there has been conflicting data reported as far as back extensors, where the Escamilla studies found no difference, while the Cholewicki group found an increase in spinal erectors (T12 and L3 paraspinal activity).

Both of the exercises use the hamstrings/hip extensors as agonists, both as primary movers and in synergism for contradirectional lumbopelvic rhythm...there is some dynamic stabilzation in sacroilliac nutation torque, but I wouldn't really consider that in terms of "primary classification" of the function of the hamstrings during the exercise.
 
My word useage was lacking there to say the least.

Interesting, I will look in to those studies :)

The area I was coming from (and I am guessing these studies will debunk that) was since the sumo decreases hip flexion and more upper trunk movement that in the angle would provide for more hamstring involvement over the conventional deadlift.

I will hit up those studies, Thanks for the heads up there.
 
Deadlifts

Sumo deadlifts start with much larger joint angles. Most beginners find that they can sumo more weight than they can conventional.

The technique is easier and it is easier to keep the low back tight in the sumo deadlift.

Conventional deadlifts train more low back because you are bent over more at the hip. As opposed to staying more upright in the sumo style.

If you are a well rounded lifter the weight you lift will be pretty close to the same in both lifts.
