Your ankles collapse in squats because your foot isn't stable. Fix it in two steps: roll a lacrosse ball on your foot and ankle for 90 seconds, then do a resistance band drill where you push your knees out for 30 seconds to one minute while keeping your big toe, pinky toe, and heel on the ground.

Does your ankles collapse when you squat or move like this? We're going to fix it. Now, your foot and ankle, they need 3 points of contact to create stability: the big toe, the pinky toe, and the heel. This creates a tripod of stability and strength. The first thing we're going to do is we're going to mobilize the tissue by rolling it with this lacrosse ball. Now, you could do this standing or just put pressure on in a kneeling position. It's completely up to you, but you got to do it for 90 seconds to 2 minutes. Now, once you've done that, we got to strengthen the area. That's where this band comes in. You want to use your lightest band. You're going to keep your feet straight and then drive your knees outside your toes against the band. This is going to rotate your shin bones and create this nice little pretty arch here. Now you're going to do that and hold for 30 seconds to a minute and make sure your big toe, your pinky toe, and your heel are all making contact and then relax. With proper mobility and stability and the strengthening, you should get rid of that collapsing ankle and feel a lot more strong, stable, and explosive.
