The bar cant be in front of you. That defies the laws of physics the bar must always be over your feet or you will fall over

The only variables are the degree of knee, hip and lumbar flexion

It feels like it goes further in front of you, because you're breaking more at the knees which allows you to push your hips further back. Obviously you can't actually hold the bar in front of you with any reasonable weight.

And yeah, obviously those are the only variables. Those are the only joints that can vary.

If you are more flexed at the hips/pushing your hips further back its because your knees are staying straighter not breaking more
If you are bending more at the knee, your torso will be more upright and the degree of hip flexion less

Im assuming you are calling no 1. RDLs and no 2. conventional deadlifts, but really there is no strict demarcation between the two, which is why I ask what people mean by that term "RDL"

Stiff-leg deadlifts/straight leg deadlifts i presume you are specifying that there must be ZERO knee flexion

Yes, that's right.

the fact that you've bent your knees means that the working angle of the weight is smaller, so the back has less work, and the hamstrings aren't all that involved. The hamstrings aren't all that involved in SLDLs either tbh. It's mainly a stretch reflex.

Im pretty confident that is completely wrong

well, try them both and see what you think.

Sure maybe it made my back a bit bigger and maybe traps, but they were still small. I betcha doing heavy bent over rows would give me way bigger growth.


Having a big bench press is to impress all the high school boys. Having a big deadlift is to impress all the lifting bros. :fonz:

And curls are for the girls or what?
post #53695 of 57262
Oh wait i misread you thats mostly correct

My question is what are people doing when they say rdl: just less knee flexion than they usually use?

The more flexed the hip, the greater torque required to extend it

A lower hip position is always mechanically advantageous its simple physics

(Assuming a neutral spine and comparable limb lengths and proportion)

Reasonably accurate explanation

it seems you have not understood any of the conversation. It's not about what's mechanically advantageous, we're not trying to lift the most weight here. I'm simply stating which variation targets which muscle groups.
post #53697 of 57262
It appears that I butted in on the conversation. I was simply explaining the difference between RDLs and SLDLs.

Obviously I'm not telling people to do conventional deadlifts like SLDLs. That's madness.
post #53698 of 57262
Yes I edited I said I misunderstood you

Im not sure that SLDLs or RDLS necessarily target any muscle group more or less (except quads perhaps), as the mechanical disadvantage simply means less weight is used?

Hamstrings and glutes are both being used to extend the hips.

Or are you daying that the hamstrings are disadvantaged to a greater extent because of the lengthening due to less knee flexion?
post #53699 of 57262
I still dont understand deadlifts. I just keep the weights light, the reps high and my spine neutral. My body has a motor pattern for deadlifts I'm too lazy to fix.... I am just going to stick with that. Its too much. How much quad do you use? Sumo or conventional? Straight spine or a little flexion? IDK I just want bigger hams. Unless u are competing its not worth agonizing over. Coldsnap has it right. Tossing heavy deads was a huge step in embracing my inner bro and shit has been a lot more satisfying and injury free.
post #53700 of 57262
If you're not powerlifting/want to get a bigger deadlift. I would probably stick with stiff legged deadlift. I would never skip all deadlifts variation though, it is a good movement when done properly.

There's plenty of dudes deadlifting reasonable amount without any size to show it off (Johnny Candito and Omar Isuf comes to mind). There's also plenty of big dude that deadlift heavy often. But then again, what size can you really get at 160-180 lbs natty?

just my 2 cents
