What should I feel during Pendulum squat?

Deep quad burn through full ROM — machine arc removes balance demand entirely.

What are common mistakes with Pendulum squat?

Shallow depth — machines support full ROM, use it; Heels lifting — move feet higher on platform; Locking out with high spinal load — keep arch neutral

How do I progress Pendulum squat?

Add weight once full-depth 3×10 is consistent.

What can I do instead of Pendulum squat?

Hack squat, Leg press, Safety bar squat
