Lever Seated Twist
The Lever Seated Twist primarily works the External Obliques, with secondary activation of the Erector Spinae, Iliopsoas, Quadratus Lumborum and stabilizer support from the Adductor Magnus, Anterior Deltoid, Brachialis, Latissimus Dorsi, Pectoralis Major (Clavicular), Pectoralis Major (Sternal), Pectoralis Minor, Posterior Deltoid, Rhomboids, Trapezius (Lower), Trapezius (Middle), Triceps (Long Head). It is a machine isolation exercise at beginner difficulty.
The Lever Seated Twist is an beginner isolation exercise performed with machine, following a rotation movement pattern. It primarily targets the External Obliques, with secondary engagement of the Erector Spinae, Iliopsoas, Quadratus Lumborum. This is a bilateral pulling movement, engaging both sides of the body simultaneously.

Muscles Worked
The External Obliques is the primary mover, taking on the bulk of the workload throughout the full range of motion. The Erector Spinae, Iliopsoas, and Quadratus Lumborum act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output. The Adductor Magnus, Anterior Deltoid, Brachialis, and 9 other muscles act as stabilizers, maintaining joint position and postural alignment throughout the movement.

How to Perform
Preparation
- Adjust range of motion setting on machine to one side.
- Sit with legs against padding.
- Place torso against pad and grasp handles.
Execution
- Rotate torso through waist to opposite side.
- Return and repeat.
- Adjust range of motion setting to opposite side and repeat in opposite direction.
Comments
- SeeSpot Reduction Myth.
Tips & Common Mistakes
- Initiate rotation from your hips and torso, not just your arms.
- Control the return movement — resist letting momentum do the work.
- Keep your core engaged throughout to protect your spine during rotation.
Programming Suggestions
Adapt your sets and reps to your training goal. As a beginner-friendly exercise, start with lighter loads and focus on form before progressing weight.
| Strength | 3–4 sets × 6–8 reps at 75–85% 1RM with 90–120 seconds rest. |
|---|---|
| Hypertrophy | 3–4 sets × 10–15 reps at 60–75% 1RM with 60–90 seconds rest. |
| Endurance | 2–3 sets × 15–25 reps at 40–60% 1RM with 30–45 seconds rest. |
Alternative Exercises
These exercises target the same primary muscles (External Obliques) and can be substituted based on your equipment or variation preferences.
