Anyone do many concentric repetitions of these? I've done them at times but only for a change, never regularly.
I wouldn't waste my time really
Can depending on the equipment available and the type of training you do. They're probably one of the hardest bodyweight exercises to do when done properly and you need very little equipment. I think I get a better stretch in the hams doing these than SLDL's
Its unlikely you get a better stretch as the hamstrings never get anywhere near their end range in a Nordic/inverse curl.
definitely get a greater contraction though.
theres a lot of evidence suggesting that activity levels in the different hamstrings (biceps femoris vs semitendonosis/membranosis) differ depending on whether the exercise is hip extension or knee flexion based, and that even whether the proximal or distal fibres activate most is exercise dependent (in other words to work the 'whole length' of the hamstrings you need a variety of exercises)
Eccentric knee flexion strength is also one of the few semi reliable predictors of risk factor of hamstring injury in athletes
How is there a stretch?
if you do them properly the hip stays in extension
There is no rotation or movement at the hip at all (looking at the vid) the ham's attaching to the lower leg as that dude approaches (lowers) to the floor the hamstring extends.
this is not a good exercise for strengthening the hamstring its more a exhibition of strength an accident waiting to happen
