Trunk Bracing

A strong glute contraction should be felt in the lifted position. Pressing the wall-side foot should create glute engagement on that same side. In the demonstrated setup, the working sensation should be felt in the left glute. Bracing helps keep the trunk organized while the hips move backward. Feeling the top-side glute working indicates that the position is being held correctly. A back pocket tuck helps engage the glutes. The inhale phase uses glute squeezing to create tension. The drill calls for lightly squeezing the glutes on the inhale. Squeezing the foam roller with both knees is part of the muscle-engagement strategy. The heel should press into the wall during the exercise. The drill emphasizes maintaining glute engagement while stepping forward. Heel pressure and foam roller squeeze should continue through the breathing cycle. Glute engagement should be maintained as the knee drives forward onto the box. Glute engagement creates active tension rather than passive hanging into the stretch. When the left leg presses into the wall, the intended sensation is left glute activation. Pressing one leg into the wall creates heel tension and activates the glute on that side. Each i…
