Description
A barbell one leg squat is a challenging lower body exercise that targets the glutes, quads, and hamstrings. It is performed with a barbell and requires balance and strength.
How to Do Barbell One Leg Squat
- 1Setup
Load a barbell onto a squat rack and position it across your upper back, just below your neck, gripping it wider than shoulder-width.
- 2Setup
Step away from the rack, place your feet hip-width apart, and then lift one foot off the ground, extending it slightly forward or backward for balance.
- 3
Inhale and slowly lower your body by bending the knee of your standing leg, keeping your chest up and back straight, until your thigh is parallel to the floor or slightly below.
- 4
Ensure your knee tracks over your toes and does not collapse inward, maintaining balance throughout the descent.
- 5
Exhale and powerfully drive through your standing heel to return to the starting position, extending your hip and knee fully.
- 6
Complete all repetitions on one leg before switching to the other leg to ensure equal work and maintain focus.
Tips
- Focus on a stable gaze point: Pick a spot on the floor or wall in front of you to help maintain balance throughout the entire movement.
- Engage your core: Actively brace your abdominal muscles to stabilize your torso and prevent excessive leaning or swaying.
- Control the eccentric phase: Slowly lower yourself into the squat over 2-3 seconds to maximize muscle tension and improve stability and control.
- Use a spotter or power rack: Due to the high difficulty and balance requirement, use safety pins in a power rack or have a spotter nearby for safety.
Common Mistakes
- ×Losing balance: People often rush the movement or don't engage their core, which causes instability; fix this by performing the exercise slowly and deliberately, focusing on a fixed point, and bracing your core.
- ×Knee caving inward: Allowing the standing knee to collapse inward (valgus collapse) can stress the joint; fix this by actively pushing your knee slightly outward to align it with your foot throughout the squat.
- ×Rounding the back: Failing to maintain a neutral spine can lead to injury and reduce effectiveness; fix this by keeping your chest up and shoulders back, engaging your core to maintain a straight back.
