Do you ever get a pain in the butt that feel is like it’s your hamstring but super high in the bum. Like right in there! It could be an issue with the tendon at its insertion point. If that sounds like you give this exercise ago. It makes the muscle and tendon work at the most common point of injury. The isometric portion. Between the contraction and the release phase of a movement. This long lunge reached the muscle and tendon to manage the high forces in the isometric hold inbetween changes of direction. it’s also really good for building into front splits ☺️
