Lever Neck Flexion (plate loaded)
The Lever Neck Flexion (plate loaded) primarily works the Sternocleidomastoid and stabilizer support from the External Obliques, Latissimus Dorsi, Posterior Deltoid, Rectus Abdominis, Rhomboids, Trapezius (Lower), Trapezius (Middle), Triceps (Long Head). It is a machine isolation exercise at beginner difficulty.
The Lever Neck Flexion (plate loaded) is an beginner isolation exercise performed with machine, following a isolation movement pattern. It primarily targets the Sternocleidomastoid. This is a bilateral pulling movement, engaging both sides of the body simultaneously.

Muscles Worked
The Sternocleidomastoid is the primary mover, taking on the bulk of the workload throughout the full range of motion. The External Obliques, Latissimus Dorsi, Posterior Deltoid, and 5 other muscles act as stabilizers, maintaining joint position and postural alignment throughout the movement.
Primary Muscles
- Primary Muscle Sternocleidomastoid (neck)
Stabilizer Muscles
- Stabilizer Muscle External Obliques (core)
- Stabilizer Muscle Latissimus Dorsi (back)
- Stabilizer Muscle Posterior Deltoid (shoulders)
- Stabilizer Muscle Rectus Abdominis (core)
- Stabilizer Muscle Rhomboids (back)
- Stabilizer Muscle Trapezius (Lower) (back)
- Stabilizer Muscle Trapezius (Middle) (back)
- Stabilizer Muscle Triceps (Long Head) (triceps)
How to Perform
Preparation
- Sit on seat in machine.
- Position padded lever on face.
- Position body so neck is in line with lever axis.
- Grasp handles for support.
Execution
- Move head forward by flexing neck until chin touches upper chest.
- Return head by hyperextending neck and repeat.
Tips & Common Mistakes
- Use a full range of motion — partial reps reduce stimulus on the target muscle.
- Slow down the eccentric (lowering) phase for greater time under tension.
- If you need to swing or cheat, the weight is too heavy — reduce and focus on form.
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 (Sternocleidomastoid) and can be substituted based on your equipment or variation preferences.
