Single-leg squats are great—but adding a stability ball against the wall changes the challenge.
The ball provides just enough support to improve balance, allowing you to focus on:
✅ Keeping the pelvis level
✅ Preventing the knee from collapsing inward
✅ Building strength in the gluteus medius, which helps stabilise the hip during walking, running and single-leg movements
💡 Cue: Push through your whole foot, keep your knee tracking over your second toe, and think about pushing your hip into the wall slightly as you stand.
Remember: The gluteus medius isn't the only muscle responsible for knee or hip stability, but strengthening it can improve control and reduce excessive movement during single-leg tasks.
Save this exercise and add 2–3 sets of 8–12 reps per side to your lower-body workouts.
