What do I need to work on / what weakness does that indicate?
I can do both back and front lunges no problem. Coming out of a back lunge there's no issue, can bring the back leg straight up into a kick then back to the lunge in one movement.
But a front lunge is different. When I bring the front foot back up, I feel like I'm having to slightly arch the back and even then I'll usually have to put the foot down. Is it weakness in the core? Or the hips? I can't work out why it's so hard!
I do have poor ankle flexibility (can't squat low as heel doesn't stay on floor), maybe it's that because the back foot/ankle isn't strong enough to take the strain once front foot comes off the floor?
