Squat Technique: Using Your Adductors as a Secret Weapon
Summary
Strong quads, glutes, and hips aren’t always enough to break through a squat plateau. According to Jeff Cavaliere of ATHLEAN-X, the adductors (inner thigh muscles) are a critically overlooked source of squat power. Training them in a functional, closed-chain position can unlock a powerful stretch reflex that drives you out of the bottom of your squat.
Key Points
- The adductors are the hidden weak link in many lifters’ squats — even those with well-developed quads, glutes, and hips
- The adductors attach from the inside of the pelvis down to the inside of the leg near the knee, and are placed under a deep stretch when the knees travel out at the bottom of a squat
- Adequate adductor flexibility is a prerequisite — groin stretching and lateral lunge stretching help ensure the muscle can reach full depth without restriction
- At the bottom of a squat, a well-stretched adductor creates a stretch reflex that contributes to powering you out of the hole
- The adductor machine at the gym offers little functional carryover — closed-chain, foot-on-ground training is far more effective for athletic strength development
- A simple diagnostic test: squat with knees tracking out over toes for an entire workout — unexpected soreness in the inner thigh/groin the next day confirms your adductors are undertrained
- The adductors are part of the kinetic chain — weakness here reduces power output throughout all lower body movements
Exercise Details
Sliding Adductor Squat (Hardwood Floor Drill)
Target Muscles
- Primary: adductors (inner thighs)
- Secondary: quadriceps, glutes
Setup
- Perform on a hardwood floor or tiled surface in socks, or place weight plates on carpet and stand on the plates to allow foot sliding
Proper Form Cues — Progression
Level 1 — Basic Slide:
- Stand with feet together
- Let feet slide outward, then squeeze legs back together using adductor activation
- Focus on feeling the contraction on the way in
Level 2 — Sliding Squat:
- Slide feet out wide
- Drop down into a mini squat, actively pushing knees out to load the adductor stretch
- Simultaneously contract quads, glutes, and adductors to drive back up and slide feet together
- Key cue: all muscles fire at once to power out of the bottom position
Common Mistakes to Avoid
- Allowing knees to cave inward during the descent — knees should track outward
- Neglecting adductor flexibility work, which limits how much stretch reflex is available at the bottom
- Relying solely on isolation machines (e.g., the seated adductor machine) instead of functional movement patterns
Sets/Reps
- No specific sets or reps prescribed; introduced as a corrective drill and movement primer to be incorporated into training
