How to do pendulum squat
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
The Pendulum Squat is a favorite among bodybuilders and strength athletes for one reason: it targets the quads with incredible precision. Unlike a traditional barbell squat, the machine moves in an arc (a pendulum motion). This arc mimics the natural path of a squat but removes the balancing act required by a free bar.
Because the machine supports your back and guides your path, you can place your feet lower on the platform to emphasize the quads or higher to involve the glutes. It is particularly famous for allowing 'ass-to-grass' depth without the lower back rounding (butt wink) that often happens in free-weight squats.
Why Use It
- **Extreme Depth:** The arc-like path makes it easier to get deep into the squat without losing your form.
- **Back Safety:** Your torso is supported, taking the stress off your spine and putting it on your legs.
- **Quad Emphasis:** Excellent for building the 'teardrop' muscle above the knee.
When to Use It
Use this as your primary leg movement or as a secondary 'heavy' accessory after barbell squats.
Instructions for Proper Form
Setup
- Step In: Position yourself under the shoulder pads and press your back firmly against the backrest.
- Foot Placement: Place your feet shoulder-width apart on the platform.
- Unrack: Drive upward slightly to release the safety handle.
Execution
- The Descent: Slowly lower yourself. Because of the pendulum arc, you will feel your hips move back and down.
- The Bottom: Go as deep as your mobility allows—ideally until your thighs pass parallel.
- The Drive: Push through your mid-foot and heels to return to the start.
Pro Tip: Imagine you are trying to push the platform away from you rather than just standing up.
Common Mistakes
- Heels Lifting: This puts excessive stress on the knees. Move your feet slightly higher on the platform if this happens.
- Short Reps: Stopping at parallel. The Pendulum Squat is designed for depth—use it!
- Soft Core: Forgetting to breathe and brace, which can make the movement feel unstable.
Mistakes by Level
Beginner
- Setting feet too low, causing heel lift.
- Not using the full range of motion.
Intermediate
- Rushing the eccentric (lowering) phase.
- Locking knees too hard at the top.
Advanced
- Using too much weight and sacrificing depth.

Setup Requirements
- Adjust the shoulder pads to fit your height.
- Position your feet on the platform (lower for quads, higher for glutes).
- Ensure the safety catch is easy to reach.
Form Checklist
- Are your heels staying down?
- Is your lower back staying flat against the pad?
- Are you using the full range of motion?
Range of Motion
Full knee and hip flexion. Aim to get your hamstrings to touch your calves at the bottom.
Breathing Pattern
Big inhale and brace your core at the top; exhale as you drive out of the bottom.
Tempo Guidance
3 seconds down, a 1-second pause at the bottom, and an explosive drive up.
Caution Notes
- Don't lock your knees out aggressively at the top; keep a 'soft' lockout to maintain tension.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.
Best For
- Building massive quads.
- Lifters with lower back issues who still want to squat heavy.
- High-intensity training (HIT).
Goal Tags
Rep Ranges
- 6-10 reps for strength and size.
- 10-15 reps for hypertrophy and endurance.
Set Guidance
3-4 sets.
Rest Guidance
2-3 minutes (this is a demanding lift).
Frequency
1-2 times per week.
Pairings
- Pair with Leg Curls or RDLs for a complete leg day.
- Follow up with Leg Extensions for a final quad burnout.
Audience Notes
- Intermediate to advanced lifters will get the most out of this machine's unique mechanics.
Substitution Targets
- Hack Squat
- Leg Press
- Barbell Squat
Variations
Use progressions to increase difficulty when you master the movement, and regressions if you struggle with proper form or face mobility limitations.
Regressions
Leg Press
Provides similar leg drive with even more stability.
Best for: Beginners learning to drive with their legs.
Progressions
Pause Squats
Pausing for 2 seconds at the bottom removes all momentum.
Best for: Building incredible 'out-of-the-hole' strength.
FAQ
Common Questions
How is this different from a Hack Squat?
A Hack Squat moves in a straight diagonal line, while a Pendulum Squat moves in an arc. The Pendulum often feels more 'natural' on the lower back and allows for more depth.
