I have very poor hamstring flexibilty and have been trying to improve it using the stretchs in Greg Everetts book.
Im not sure If I'm hitting them too hard but they affected by last training session. I felt twinges during extension and my lower hamstrings felt destroyed the day after.
I had been doing the stretches every evening after a hot bath before going to bed. I'm not sure if its just me adapting to the mobilty regime or if I should scale back the streching to every training day after training (4 days per week)?
Also I'm curious as to why my squat is apparently unaffected by the tight hamstrings? I can maintain a tight back to full depth and can perform a squat jerk with good form.
