1) in hams stretches positions, knee must be locked or slightly bent?
I've read that tension must be felt in the mid of hams, not in the rear of knee.
It's right? It's tension in the rear of knee a sign that you're stretching tendons?
Other sources instead says that tension must be felt in the rear ok knee.
who's right?
2) about knees, are they more vulnerable in locked position or in the slightly bent position?? ( for example, in isometric side split contraction )
thanks for replyes, and sorry for my terrible english
