For hamstrings I just sit on the floor with extended legs and then lean forward to touch my toes. Unfortunately, I don't get the stretch feeling at all, instead am feeling an extreme stretch kinda behind my knee. Problem with this is that the stretching pain is definitely much harder than anywhere else. Is that normal for a beginner? Do I just have to stand through this or is something wrong? Maybe some sort of dysbalance between front and back thigh strength? hope some may know what it might be...
sorry for the english, i'm german, so not really a regular speaker
