just looking for suggestions for leg workouts/stretches or anything like that to gain flexibility in your legs. ive been working on the rubber guard alot and i always use it when im rolling/doing bjj, im tall and have long legs so getting the rubber guard and maintaining the position is no problem at all. i just find that people that are alot stronger than me can posture a bit too easily and break it. would more work on flexibility help this? or should i just work on getting stronger and better techniques to keep my opponent down better?
