1
Sit upright on the bench with your back firmly against the backrest, feet flat on the floor or footrest, and knees positioned at 90 degrees. Hold the barbell across your thighs just above the knees with both hands using an overhand grip, shoulder-width apart.
2
Position the loaded barbell securely across the top of your thighs near the knee joint. Ensure your torso remains upright and braced against the bench. Grip the bar firmly with both hands to maintain control throughout the movement.
3
Slowly lower the barbell by extending your knees, allowing your legs to straighten until nearly full knee extension is achieved. Control the descent by resisting gravity, maintaining tension in the quadriceps throughout the lowering phase. Do not lock out completely at full extension.
4
Drive the barbell upward by contracting the quadriceps and flexing your knees, returning to the starting position with knees bent at approximately 90 degrees. Exhale during this concentric phase, squeezing the quads at the top of the movement before repeating.
