Bodyweight Squat (Air Squat)

SquatBW

The foundational bodyweight squat pattern — feet shoulder width, descending to at least parallel and standing back up with no external load. The base regression for all loaded squat variations.

Demo: Untamed Strength

Sets

3

Reps

12-20

Rest

45s

Contraindications

Very low risk for most populations — a good diagnostic movement for assessing ankle/hip/knee mobility before loading.

Setup

Stand with feet shoulder-width apart, toes slightly turned out, arms extended forward or held at chest for balance.

Execution

  1. 1Initiate the movement by pushing the hips back slightly and bending the knees
  2. 2Descend until thighs are at least parallel to the floor
  3. 3Keep the chest up and heels planted throughout
  4. 4Track the knees over the toes without collapsing inward
  5. 5Drive through the whole foot to return to standing

Key cues

  • Sit down between the heels, not straight back
  • Chest up, proud posture throughout
  • Knees track over the toes
  • Heels stay planted on the floor
  • Drive through the whole foot on the way up

Common faults

  • Knees caving inward (valgus)
  • Heels lifting off the ground
  • Excessive forward torso lean
  • Butt wink (lumbar flexion) at the bottom
  • Shallow depth — not reaching parallel

Tweaks

  • Add a pause at the bottom for tempo work
  • Elevate the heels slightly for ankle-limited individuals
  • Progress to goblet squat once form is consistent

Regressions

Progressions

Muscles

Primary: Quadriceps, Gluteus Maximus

Secondary: Hamstrings, Core, Calves

Notes

Serves as the base regression for the entire squat family tree — mastery here should precede all loaded variations.
