How tight / flexible should hams be for optimal lower posterior chain?
I have read more and more regarding hamstrings needing a certain amount of tightness ( and not TOO much flexibility ) so the lower posterior chain has a certain amount of loading/tension and so can pull stronger and more efficiently… but at same time, being too tight doesn’t seem/feel right either as tightness seems to prevent getting into good biomechanical positions and seems to put too much tension on pelvis/lower back.
Is there a consensus that in that hams can be in fact “too flexible” for effective pulling with lower posterior chain?
If so, any thoughts/guidelines as to zeroing in on an optimal amount of flexibility so can get comfortably into good mechanaical position but still enough tension for a strong pull with the lower posterior chain?
If someone has thought about about this, I would be interested to hear about a decent metric in regards to the “correct” amount of flexibility.
I’ll throw out that maybe “just barely” being able to grasp lower/mid shin with straight/stiff legs might be about right amount of flexibility? more/less? I know I should go by probably go by “feel”… but I just ain’t feeling it so far! But, I think I may be erring on the tight side so far.
