sorry if this is the wrong forum, i am new to the site...
so i started doing the natural glute ham raise (from the floor). the first week i only did 4 half reps. the next week i knocked out 10 full reps with a couple attempts to failure. since that time i have been playing plenty of sports with no pain... however my hamstrings (especially my left one) has a constant feeling of tightness. how do i distinguish between a tight hamstring and a strained hamstring?
my third week doing the natural glute ham raise, my hamstrings (especially the left) felt weak and i only did 4 half the way down. my forth week when i tried doing it my hamstrings felt quite bad, and my left hamstring immediately cramped up and was very tight for a couple of days.
why would my hamstring get worse with time not better? thoughts on treating it? thanks.
