The difference is that when the opponent's fingers are at the level of your thumb, that's the most precise representation of what devon's lift trains. BUT if you're facing a rising-based toproller, then his fingers are higher than your thumb. That's why i believe that both pronation through the thumb and rising based pronation through the index finger knuckle should be trained
This is a very interesting topic, my theory is that it all comes down to where the opponent grab your hand by. If they grab you high on te hand you will have to express te pronation though the hand, and you they grab you low, making more contact with the meaty part of the thumb and the wrist, you'll have to do it through the thumb. Would be interesting to make a video comparing posting toprollers or puller with a shorter arm an smaller hand that use more side pressure like Hutchings, Arsen Liliev and Travis Bagent, to lowand toprollers or toprollers with a longer arm and more dominant hand in general, like Vitaly, Devon, and John (not a long arm but a dominant hand) to see if this theory is true or not.
When you are doing pronation lifts trough the hand dynamically(meaning you are going from palm up to a pronated position) if you place the strap near the index knucle you are training much more the flexor carpi radialis, specially if you are flexing your wrist cause the pronator loses leverage. Great exercise but trains different muscles. Pronations happens at the elbow joint, so taking the strap higher on your hand just increases the leverage on your wrist flexors, and makes the pronator less involved.
You can't look at a match and say "there is no contact with the hand" and then conclude that they aren't using their hand to pronate. If you pronate through the hand you wouldn't get any contact with your opponent as pronation is going away from them.
I disagree with what you said about todd not using a lot of wrist flexion. Just because his wrist is a bit bent back doesn't mean the opponent completely cracked his wrist. He's still putting massive pressure through his wrist.
Thank you for making this video. if I understand right, it means they both have their pros so it's not that One type is much better than the other, Pronation through the thumb is more if you rely on your wrist, and through the fingers is if you're less rely on the wrist, but overall it doesn't matter so much because the Pronation doesn't cross the wrist, but the cons is what you said in the video with the high pronation that it's can be easy to cheat so you reccemmond through the wrist. But I think 2 cons that it has, It can be hurt on the wrist if I use heavy weights, and second it's more low Pronation so it's more effective in low hand toproll and in hook
I have never felt my pronation working when I try the belt on the wrist, only the discomfort of the belt on the wrist. I don't think it makes that much sense to train with the belt on the wrist, because in a match you're holding on to your opponent with your hand, so it's better to train using the hand. Maybe I need to find a more comfortable way to have the belt on the wrist if it really is superior for targetting pure pronation.
