Pendulum Squat
The Pendulum Squat primarily works the Gluteus Maximus, Rectus Femoris, Vastus Lateralis, with secondary activation of the Vastus Medialis and stabilizer support from the Rectus Abdominis, Transverse Abdominis. It is a machine compound exercise at intermediate difficulty.
The Pendulum Squat is a intermediate compound exercise performed with machine, following a squat movement pattern. It primarily targets the Gluteus Maximus, Rectus Femoris, Vastus Lateralis, with secondary engagement of the Vastus Medialis. This is a bilateral pushing movement, meaning both sides work together to generate force.
Squat with the machine in a pendulum motion, allowing for unique loading patterns.

Muscles Worked
The Gluteus Maximus, Rectus Femoris, and Vastus Lateralis are the primary movers, collectively driving the movement and absorbing the greatest share of the load. The Vastus Medialis assists as a secondary mover, contributing to force production without bearing the primary load. The Rectus Abdominis, Transverse Abdominis act as stabilizers, maintaining joint position and postural alignment throughout the movement.
Primary Muscles
- Primary Muscle Gluteus Maximus (glutes)
- Primary Muscle Rectus Femoris (quadriceps)
- Primary Muscle Vastus Lateralis (quadriceps)
Secondary Muscles
- Secondary Muscle Vastus Medialis (quadriceps)
Stabilizer Muscles
- Stabilizer Muscle Rectus Abdominis (core)
- Stabilizer Muscle Transverse Abdominis (core)
How to Perform
Preparation
- Adjust machine seat and pads to fit body.
- Sit or position body in machine.
Execution
- Bend at hips and knees, lowering body until thighs are parallel to floor.
- Drive through feet to return to standing position.
- Repeat.
Comments
- Maintain control throughout movement to fully engage the Rectus Femoris, Vastus Lateralis, Gluteus Maximus.
Tips & Common Mistakes
- Keep your chest up and spine neutral throughout — avoid rounding your lower back.
- Push your knees out in line with your toes as you descend.
- Aim for at least parallel depth — cutting squats short reduces muscle activation.
Programming Suggestions
Adapt your sets and reps to your training goal.
| Strength | 3–5 sets × 3–6 reps at 80–90% 1RM with 2–4 minutes rest. |
|---|---|
| Hypertrophy | 3–5 sets × 6–12 reps at 65–80% 1RM with 60–120 seconds rest. |
| Endurance | 2–4 sets × 15–20 reps at 50–65% 1RM with 30–60 seconds rest. |
Alternative Exercises
These exercises target the same primary muscles (Gluteus Maximus, Rectus Femoris, Vastus Lateralis) and can be substituted based on your equipment or variation preferences.
