Just reading the Glute ham raise thread. doing GHRs I always got very sore gastronemius and less sore sore hamstrings.
I find however that the OL second pull , gives me sore tight hamstrings (in a good way as opposed to injured).
CV deadlifts have not give me any hamstring soreness in a long time. I thought I had strong hamstring due to this. Doing OL pulls I am finding my hamstrings may be the weak link.
maintaining a flat back is so hard and energy sapping when the weight gets heavy.
