Bulgarian Knee Locker (pair)

Lock your back leg in, isolate the front one. The Spartaks Bulgarian Knee Locker secures your back leg in position during Bulgarian split squats, eliminating the wobble that comes from balancing on an unsupported bench or box edge. Sold as a pair, they bolt directly to your rack uprights for a stable, repeatable setup every session.

A padded contact surface protects your knee and shin through high-rep or weighted sets, and the mounting height adjusts to fit your body and training style. Bolts to any 3"×3" rack with 1" hole spacing.

• Bulgarian Split Squats — The primary use case: a stable, locked-in position for your back leg through every rep.
• Single-Leg & Elevated Lunge Variations — Supports elevated lunges and other single-leg squat patterns that benefit from a fixed back-leg position.
• Rehab & Balance Work — A stable anchor point for unilateral leg work during rehab or balance-focused training.
• Lat Pulldowns — Lock yourself in place during seated lat pulldowns to stay anchored through heavy pulls.
