The single leg squat with miniband, also known as an assisted pistol squat, is an advanced unilateral exercise where you squat on one leg while the other leg extends forward off the ground. Looping a mini resistance band above the knees adds constant outward tension, forcing the hip abductors and glute medius to actively resist the band collapsing your knee inward. It demands significant quadriceps and glute strength along with balance and ankle mobility, making it a benchmark single-leg exercise for intermediate and advanced lifters.
Muscles Targeted
- Primary: Quadriceps, glutes
- Secondary: Hip abductors (gluteus medius), hamstrings
- Tertiary: Core, ankle stabilizers, calves
Starting Position
Loop a mini resistance band around both legs just above the knees. Stand tall on one leg with the opposite leg extended straight out in front of you, arms raised forward for counterbalance. Keep a slight bend in your standing knee, your chest up, and your core braced before beginning the descent.
Execution Steps
- Extend your non-working leg straight out in front of you, holding it off the floor throughout the set
- Push your hips back and begin bending your standing knee, keeping the band taut against outward knee pressure
- Lower under control, letting your arms rise forward as your hips drop to counterbalance your weight
- Descend as deep as your mobility allows, ideally to the point where your hamstring nears your calf
- Drive through your standing heel to reverse the movement and stand back up
- Keep your extended leg off the ground for the entire set before switching sides
- Repeat for the desired reps, then switch legs and repeat with the same band tension
Form Cues
- Push the knee out into the band: Actively resist the band pulling your standing knee inward
- Keep your heel planted: If your heel lifts off the floor, you've likely gone deeper than your current mobility allows
- Use your arms for balance: Let them rise and reach forward as a natural counterweight during the descent
- Brace your core: A tight midsection keeps your torso from twisting as you balance on one leg
- Control the descent: A slow, deliberate lowering phase builds far more strength than dropping quickly into the bottom
Common Mistakes
- Letting the heel lift off the ground during the descent, which shifts stress to the toes and increases fall risk
- Allowing the knee to cave inward against the band instead of actively pushing outward, defeating the purpose of the band
- Rushing to full depth before you have the mobility or strength, causing loss of balance
- Using momentum or a bouncing motion at the bottom instead of a controlled, strength-driven ascent
- Leaning too far forward, which turns the movement into a hip-dominant hinge rather than a true squat
Variations
- Box-assisted single leg squat: Squatting to a box or bench reduces range of motion for those building toward a full pistol squat
- TRX-assisted single leg squat: Holding suspension straps provides upper-body support to offset balance demands
- Skater squat: Bending the rear knee toward the floor instead of extending it forward reduces hamstring flexibility requirements
- Bulgarian split squat with band: A more stable two-point-of-contact alternative with the same band-driven hip abduction cue
- Weighted single leg squat: Holding a light dumbbell or kettlebell once bodyweight reps are controlled and strong
Tips for Progression
- Start with box-assisted or TRX-assisted reps and reduce the assistance as strength and balance improve
- Increase band resistance gradually once you can complete full sets with good knee tracking
- Add a 1-2 second pause at the bottom position to build strength through the deepest part of the range
- Increase reps toward 8-10 per leg with strict form before adding external weight
- Progress to a heavier band or a light dumbbell once the standard version feels controlled
Training Notes
Train the single leg squat with miniband 1-2 times per week as a primary or secondary lower-body exercise, typically for 2-3 sets of 6-10 reps per leg. Rest 60-90 seconds between sets given the balance and strength demand. Because of its difficulty, place it earlier in a session while you're fresh, and build up through assisted variations before attempting full unassisted sets.
