box step ups

Box step ups are a great way to build strength, stability, and power. But if your knee keeps collapsing inward, you’re setting yourself up for pain.
A common issue during box step-ups and squats is knee valgus—when the knee caves in instead of staying aligned. This can lead to discomfort on the inside of your knee during or after workouts.
The good news? You can train your body to fix this pattern using a simple band technique called reactive neuromuscular training (RNT). This method helps your knees track properly, reducing strain and improving movement.
