SquatBWDBBox

Step-up performed sideways, stepping laterally onto the box rather than facing it forward. Emphasizes glute medius and frontal-plane hip stability more than a standard forward step-up.

Contraindications

Low risk when box height is regressed — commonly used in physical therapy settings for knee and hip rehab.

Setup

Stand beside a box/step. Place the near foot fully on the box.

Execution

  1. 1Drive through the foot on the box to lift the body up sideways
  2. 2Keep the working knee aligned over the ankle, resisting cave-in
  3. 3Stand to full extension at the top
  4. 4Control the descent back to the start
  5. 5Repeat on one side before switching

Key cues

  • Drive straight up, not diagonally
  • Knee stays aligned over the ankle
  • Chest proud throughout
  • Minimize push-off from the grounded leg
  • Control the way down

Common faults

  • Knee collapsing inward or outward
  • Pushing off the floor leg excessively
  • Box too high causing loss of control
  • Hips rotating instead of staying square
  • Rushing the descent

Tweaks

  • Hold a kettlebell goblet-style for load
  • Add a knee drive/balance hold at the top
  • Combine with medial-lateral band work for glute medius emphasis
