Bill D- Strong Hamstrings = healthy knees IME.
I was told I`d absolutely have to have knee replacements by now (those xrays were really scary...), and I did have to quit driving a stick (it was that or else quit lifting heavy..easy choice), but I`ve had *zero* knee issues for decades since prioritizing my Hams despite all that StairMaster work that`s supposedly hard on them (not IME).
