So many posts on lower leg stability.
It comes from the hips.
If the hips aren’t stable the legs aren’t stable
Yes as you move down the chain if there are issues within the knee or ankle they will absolutely affect the lower leg but you should always start at the hip.
Focus on your hip stability-what creates hip stability I hear you ask? Great question!
Think about the big muscle groups attached to the pelvis.
The Glutes, The Quads, The Hamstrings, The abdominals and the lower back. They all work together to create stability in the pelvis. So all exercises to train this should include movement and cooperation between these muscle groups.
Some examples:
Deadlift
Squat
Single Leg Squat
Single Leg Squat
There’s tons of things you could do these are just some of my picks.
If you think your actual lower leg may be the problem adding in exercises such as a Front leg raised Split Squat can help you to improve both mobility of the ankle and stability of the knee whilst loaded/absorbing movement.
Keep an eye out on the socials for some videos of these exercises!
