Cool, Marv. Thanks for that link. I was actually looking at the DO WINS most of all. I can't really find any addidas shoes.
I see what your problem is with the pullthroughs. I didn't explain it well before because I assumed that you were just dropping back so fast and that was the problem.
You need to lighten the weight. Do lower reps so that you can concentrate on quality.
I actually prefer the V-handle as well. That is the only thing I use. If you watch the vid you will see a difference when you switch. One thing you were doing with the rope is dropping your shoulders down more so that your hands go further toward you knees. Probably to spare the twig and berries
. As soon as you switched to the v-handle you kept your hands up toward you groin and this improved things.
But I think that the problem is you are trying to let yourself go back to the end of your range of motion. If you do that there is not way your will be able to keep your back flat...especially if it is not strong and stable enough to stop the motion by itself. Basically you go back as far as your hips will let you go and your flexible back takes over in that department and lets you go back further. Immediate solution: ONLY go back as far as you can keep your back straight. And don't look down between your legs. Keep your head straight and head neutral and your chest out and pround. Shoulders back and down. The whole thing. But also don't extend your neck like your are doing.
You have to feel the breaks being put on by the hips, glutes, and hams. You can't just ride it out until the passive tissues stop you. Because the only solution to that is to allow them to stretch out and then bounce out of it. When it comes to ROM the trick is to work only into the ROM you can control. Never work to the end of it. If you extend the ROM you extend it with control. This is kind of the difference in a way, between ROM + Mobility verus flexibility.
I'll have to do some heavy pullthroughs in a day or two and really pay attention so that maybe I can explain the way I do them better. I've stopped paying attention
. Right now I'm too wiped out and if I used light weigths that wouldn't require me to use my best technique.
