The one leg quarter squat is a unilateral bodyweight exercise that targets the gluteus maximus and quadriceps while engaging the adductor magnus and soleus for stability. By limiting the range of motion to roughly 25–30 degrees of knee flexion, it places high demand on the stance leg without the joint stress of a deeper squat. It is well suited for building single-leg stability, reinforcing proper knee tracking, and as a stepping stone toward full single-leg squat progressions.

Cómo hacer el One Leg Quarter Squat

  1. 1Stand upright with your feet hip-width apart. Shift your weight onto one foot and lift the opposite foot slightly off the floor, keeping your hips level.
  2. 2Place your hands on your hips or extend your arms forward for balance.
  3. 3Fix your gaze on a point straight ahead to help maintain balance throughout the movement.
  4. 4Initiate the squat by pushing your hips back slightly and bending the standing knee to roughly 25–30 degrees — about a quarter of the way down toward a full squat.
  5. 5Keep your chest tall, your spine neutral, and your knee tracking in line with your second toe throughout the descent.
  6. 6Pause briefly at the bottom of the quarter range, making sure your heel stays flat on the floor.
  7. 7Drive through your heel to straighten the knee and return to the starting position, squeezing the glutes at the top.
  8. 8Complete all reps on one side before switching to the other leg.

Consejos de técnica

  • Keep your stance knee tracking over your second toe at all times — do not let it cave inward, as this places unwanted stress on the knee joint.
  • Maintain a tall torso throughout; avoid leaning excessively forward, which shifts the load away from the glutes and quadriceps.
  • Press through the full surface of your foot, especially the heel, to maximize gluteus maximus and quadriceps engagement.
  • If balance is difficult, lightly touch a wall or hold a doorframe while you develop the neuromuscular control required for the freestanding version.
  • Control the descent — moving slowly on the way down increases time under tension and builds more stability than dropping quickly.

Errores comunes

  • Letting the knee cave inward (valgus collapse), which reduces glute activation and places harmful stress on the medial knee structures.
  • Going too deep beyond the quarter range, which turns the movement into a different exercise and can overload the knee before stability is established.
  • Rising onto the toes during the squat, which reduces stability and shifts the work away from the target muscles.
  • Allowing the hips to drop or rotate on the lifted side, which indicates weak hip stabilizers and compromises form on the standing leg.
  • Rushing through reps without control, which relies on momentum rather than muscle strength and limits the training effect.

Preguntas frecuentes

What muscles does the one leg quarter squat work?

The primary muscles are the gluteus maximus and quadriceps. The adductor magnus and soleus act as synergists, assisting with hip extension and ankle stability respectively.

How is a quarter squat different from a full single-leg squat?

A quarter squat limits knee flexion to about 25–30 degrees, reducing the range of motion compared to a full pistol or Bulgarian split squat. This makes it more accessible for beginners and useful for rehabilitation, while still building meaningful strength and stability in the target muscles.

Is the one leg quarter squat good for beginners?

Yes. The reduced range of motion and bodyweight load make it a practical starting point for anyone developing single-leg balance and strength before progressing to deeper unilateral movements.

How many reps should I do per side?

For strength and stability, 3 sets of 8–15 reps per leg is a common range. Work within a rep count where you can maintain proper form throughout — add reps or progress to a deeper squat as the movement becomes easy.

Can I use the one leg quarter squat for knee rehabilitation?

It is often used in rehabilitation contexts because the shallow range of motion keeps compressive forces on the knee relatively low. However, always consult a physiotherapist or medical professional before using any exercise as part of a rehabilitation program.
