Knee Dominant

Equipment: TRX
Difficulty: Advanced
Movement Pattern: Squat

The TRX KB Offset Bulgarian Split Squat is an advanced progression of the traditional Bulgarian Split Squat. Suspending the rear foot in the TRX significantly increases balance and stabilization demands, while the unilateral kettlebell load introduces an asymmetrical challenge that further stresses trunk and pelvic control. The exercise develops lower-body strength through the quadriceps, glutes and adductors while simultaneously requiring substantial core activation to resist the rotational and lateral forces created by the unstable support and offset load. For this reason, it is frequently incorporated into advanced athletic development and performance programs aimed at improving dynamic stability, balance and unilateral neuromuscular control.

Coaching Cues

Keep the pelvis level throughout the movement. Brace the core before every repetition. Maintain a stable kettlebell position without compensations. Control the descent through the front leg. Allow the knee to track naturally over the foot. Keep the chest up and the spine neutral. Drive forcefully through the front heel. Resist trunk rotation and lateral flexion throughout the set.

Common Mistakes

Losing pelvic control during the descent. Leaning toward the kettlebell side. Using the suspended leg for assistance. Allowing the knee to collapse inward. Failing to maintain core tension. Reducing range of motion because of poor balance. Rotating the torso to compensate for the offset load.
