Squat, Hinge, and Lower-Body Technique

Key Takeaways Explain This Topic AI

Squat: knee-dominant pattern; feet shoulder-width, knees track toes, neutral spine, depth to parallel or below if mobility allows.

Hinge: hip-dominant (RDL, deadlift); push hips back, slight knee bend, bar close to legs, neutral spine.

Lunge: staggered stance challenges balance; front knee ~90°, torso upright, push through front heel.

Common faults: knee valgus, heel rise, lumbar flexion under load, excessive forward knee travel without ankle mobility.

Regressions: box squat, goblet squat, trap-bar deadlift; progressions: front squat, deficit deadlift.

Squat, Hinge, and Lower-Body Technique

Quick Answer: Squats are knee-dominant—sit between heels, knees track toes. Hinges are hip-dominant—hips back, bar close, neutral spine. Fix valgus with band cues and glute activation; regress to box or goblet squats when needed. # Squat, Hinge, and Lower-Body Technique Exercise Technique is 25% of the exam. Lower-body patterns appear in nearly every coaching scenario. ISSA tests observation → cue → regression chains.

Squat Technique Checkpoints

  • Checkpoint Cue
  • Foot position Shoulder-width, toes 15–30° out
  • Brace Big breath, 360° core tension
  • Descent hips and knees flex together
  • Knee tracking over 2nd–3rd toe
  • Depth hip crease at or below knee if mobile
  • Ascent drive through full foot

High-bar back squat: torso more upright. Low-bar: more hip hinge angle.

Goblet and Box Squat Regressions

Goblet squat: dumbbell at chest counterbalances, teaches upright torso—ideal beginner pattern. Box squat: defines depth, reduces fear, limits knee shear for rehab clients.

  • Hip Hinge (Deadlift/RDL)
  • Bar over mid-foot
  • Soft knee bend (not squat)
  • Hips back, lats engaged ("protect armpits")
  • Neutral spine—no rounding under load
  • Drive hips forward to stand

Romanian deadlift: knees softer, emphasis hamstring stretch; bar stays close to thighs. Trap-bar deadlift: more knee flexion, favorable for some clients learning pull patterns.

  • Lunge and Split Squat
  • Front foot flat, rear on ball of foot
  • Torso tall, core braced
  • Lower until rear knee approaches floor without crashing
  • Front knee tracks over foot, not collapsing inward

Reverse lunge reduces anterior knee stress vs forward lunge for some clients.

Common Faults and Corrections

  • Fault Likely Cause Correction
  • Knee valgus Weak glute med Banded squats, clamshells
  • Heels rise Ankle restriction Heel wedge temporarily, mobility work
  • Butt wink Hip/posterior chain limit Adjust depth, mobility
  • Excessive lean Core weakness Goblet, reduce load
  • Worked Scenario: Novice Squat

Client leans forward, heels lift at parallel. Action: widen stance slightly, heel 0.5" board, ankle mobility drills, goblet 3×10 before barbell back squat reintroduction.

  • Safety
  • Always use collars on barbell
  • Spot squats from behind at rib cage if needed
  • Deadlift: reset each rep for beginners (no touch-and-go until proficient)
  • Exam Traps

Trap: Knees cannot pass toes myth—knee travel depends on limb ratios and is not inherently unsafe.

Trap: Rounding back on heavy deadlift—regress load immediately.

Trap: Forward lunge for client with anterior knee pain without trying reverse lunge regression.

Lower-body mastery separates competent CPTs from liability risks—memorize checkpoints and cue language.
