Lever Isolateral Lying Leg Curl (plate loaded)
The Lever Isolateral Lying Leg Curl (plate loaded) primarily works the Biceps Femoris (Long Head), with secondary activation of the Gastrocnemius (Medial), Gracilis, Sartorius, Soleus. It is a machine isolation exercise at beginner difficulty.
The Lever Isolateral Lying Leg Curl (plate loaded) is an beginner isolation exercise performed with machine, following a flexion movement pattern. It primarily targets the Biceps Femoris (Long Head), with secondary engagement of the Gastrocnemius (Medial), Gracilis, Sartorius, Soleus. This is a bilateral pulling movement, engaging both sides of the body simultaneously.

Muscles Worked
The Biceps Femoris (Long Head) is the primary mover, taking on the bulk of the workload throughout the full range of motion. The Gastrocnemius (Medial), Gracilis, Sartorius, and Soleus act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output.
Primary Muscles
- Primary Muscle Biceps Femoris (Long Head) (hamstrings)
Secondary Muscles
- Secondary Muscle Gastrocnemius (Medial) (calves)
- Secondary Muscle Gracilis (adductors)
- Secondary Muscle Sartorius (hip_flexors)
- Secondary Muscle Soleus (calves)
How to Perform
Preparation
- Facing bench, stand between bench and lever pads.
- Lie prone on bench with knees just beyond edge of bench and lower legs under lever pads.
- Grasp handles.
Execution
- Raise lever pad to back of thighs by flexing knees.
- Lower lever pads until knees are straight.
- Repeat.
Comments
- Exercise is performed on machine with two independent levers.
- Machine can also be used to performAlternating Lying Leg Curls.
Tips & Common Mistakes
- Control the eccentric phase — the lowering portion drives significant muscle development.
- Avoid momentum; focus on feeling the target muscle work through the full range.
- Full range at both ends maximizes stretch at the bottom and contraction at the top.
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 (Biceps Femoris (Long Head)) and can be substituted based on your equipment or variation preferences.
