Músculos y Anatomía

The barbell one-leg squat — also called the barbell pistol squat — is a single-leg squat to full depth performed with a barbell across the back while the free leg extends forward parallel to the floor. This is among the most technically demanding lower body exercises, requiring exceptional quad strength, hip flexor flexibility, ankle dorsiflexion, and balance simultaneously. The stance leg's quad, glute, and hamstring do all the work of supporting and moving the entire body plus the barbell through a full squat range of motion. The core and hip stabilizers work intensely to prevent the pelvis from dropping on the free leg side — this anti-lateral-tilt demand recruits the glute medius and quadratus lumborum of the working side isometrically throughout the movement.

Consejos Pro para Mejores Resultados

1Master the bodyweight pistol squat before adding any barbell load. The barbell one-leg squat is a loaded expression of single-leg mobility and strength — if you cannot perform a clean bodyweight pistol, no amount of barbell weight will correct the underlying limitations. Build single-leg strength systematically from supported to unsupported to loaded.
2Keep the chest as upright as possible throughout the descent. Single-leg squats have a strong tendency toward forward torso lean, which increases the hip extensor demand and reduces quad work. Drive the chest up and the elbows back on the bar to counteract the natural lean.
3The free leg's position is critical. Keep it extended forward as parallel to the floor as possible — not hanging at an angle. The extended free leg acts as a counterbalance that makes the movement mechanically possible. A drooping free leg shifts the center of mass and disrupts balance.

Errores Comunes que Debes Evitar

✗ Collapsing the working knee inward during the descent

Corrección: Valgus collapse on a single leg squat with barbell load is a significant knee injury risk. The glute medius of the working leg must fire constantly to stabilize the pelvis and keep the knee tracking over the toes. If the knee caves, the weight is too heavy or glute medius strength is insufficient. Regress to assisted or bodyweight single-leg work.

✗ Attempting this exercise without mastering bodyweight first

Corrección: Adding a barbell to an already dysfunctional single-leg squat pattern only amplifies the dysfunction. Complete 10 clean bodyweight pistol squats on each side before any barbell loading is considered. Use a TRX or suspension trainer, a doorframe, or holding a light counterweight for balance assistance during the learning phase.

✗ Not achieving full single-leg squat depth

Corrección: A partial pistol squat with a barbell provides far less training stimulus than a full depth bodyweight pistol. The full range — hip below knee — is what maximally loads the quad and tests the mobility prerequisites. If full depth isn't achievable, regress to a supported or elevated single-leg squat before loading.

✗ Leaning the torso excessively forward to balance

Corrección: Extreme forward lean shifts balance to the balls of the feet and makes the hip extensors rather than the quad the primary mover. A forward-lean compensated pistol squat is a different exercise than a true squat. If lean persists, use a counterweight held in front or a suspension trainer to allow more upright positioning while building the movement.

Cómo Programar el Sentadilla A Una Pierna Con Barra

Series y Repeticiones

3–5 sets of 3–6 reps per leg. Single-leg barbell squats are a maximal technical effort exercise. Low rep sets with full recovery between legs are appropriate. High rep sets degrade technique rapidly because balance and the specific joint stability demands accumulate fatigue quickly in the stabilizing muscles.

Frecuencia

1–2 times per week. The barbell one-leg squat taxes single-leg stability systems — hip, knee, and ankle stabilizers — that require more recovery time than bilateral squats. It can be programmed once per week as a primary leg exercise with a bilateral variation on the alternate leg day.

Dónde Colocarlo en tu Entrenamiento

Always place at the very start of the leg session, before any other significant lower body work. Balance, proprioception, and single-leg stability are highly sensitive to fatigue. Attempting this exercise after bilateral squats or deadlifts dramatically increases fall risk and reduces technique quality.

Cómo Progresar

Progress by adding 2.5 kg to the barbell only after achieving 5 clean reps on both sides at the current weight. Because left-right asymmetry is common, always train the weaker side first and match the stronger side to that rep count. Progression is slow — this is a technically demanding movement where months may pass between weight increases.

Variaciones y Alternativas

Bodyweight Pistol Squat

The foundational single-leg squat performed without any external load. Both arms extend forward for balance. The prerequisite for all loaded single-leg squat variations. If a clean pistol squat isn't achievable, assisted versions — using a TRX, holding a pole, or performing to a box — should be mastered first.

Bulgarian Split Squat

A split squat with the rear foot elevated on a bench. Provides similar single-leg loading without the extreme balance and hip flexor demands of a full pistol squat. Allows much heavier loading than the pistol. The most practical single-leg strength exercise for the majority of trainees.

Dumbbell Single-Leg Squat

The pistol squat performed holding dumbbells either at the sides or in front as a counterbalance. Lighter load than a barbell version and the counterbalance effect of the dumbbells held forward makes the balance component slightly more forgiving. A useful bridge between bodyweight and barbell single-leg squats.
