I've been trying to make my hamstrings more flexible to aid my development in some exercises like l-sit, press handstands, etc...
The problem is I seem to be making no progress at all. I am stretching 4 times / week after my training sessions but I don't see any noticeable changes in my flexibility. I've even tried stretching every day, a couple of times a day (without warming up) but i see no progressions in my hamstring flexibility. I've never had good hamstring flexibility, but I would reallly like to adress this issue so I could learn to progress towards exercises like v-sit and press handstands.
