Thanks a lot for the responses
I think this is beyond foam rollers, i really want to open my hips so i can have a better sumo pull. I'm relatively flexible there but just want to be super flexible, if it makes sense
I basically try to spread my legs and sit on my inner thighs/groin (rocking frog?) and the classic one leg on sofa hip flexor stretch.
Hmm i dont do static stretching before lifting (potential of loosing strength) but i'll figure something Trevor.
