Exercise guide
Lever Seated One Leg Calf Raise
- Beginner
- Isolation
- Rep-based
- Lower legs
This unilateral isolation exercise specifically targets the soleus muscle by keeping the knee bent, which mechanically inhibits the gastrocnemius. Training one leg at a time allows for a greater range of motion and helps correct strength imbalances between the left and right calves.

Setup
- Sit on the machine with your back straight and place the ball of your working foot on the edge of the footplate.
- Position the thigh pad comfortably across your lower thigh, just above the knee of the working leg.
- Grip the handles for stability and lift the weight slightly to release the safety bar.
- Keep your non-working foot flat on the floor or tucked safely away to avoid assisting the movement.
How to do it
- Inhale as you slowly lower your heel toward the floor until you feel a deep, comfortable stretch in your calf.
- Exhale and push through the ball of your foot to raise the weight as high as possible, focusing on a strong contraction.
- Hold the peak contraction at the top for one second before beginning the descent.
- Lower the weight back down in a controlled 3-second tempo to the starting stretched position.
Form checklist
- Ensure the ball of the foot is securely on the platform, not just the tips of the toes.
- Avoid bouncing at the bottom of the movement; use a dead-stop to eliminate momentum.
- Keep your torso upright and avoid using your arms to pull the weight up.
- Maintain a consistent line of force through the center of the foot.
Pro tips
- Pause for 2 seconds at the bottom stretch to dissipate the elastic energy in the Achilles tendon, forcing the soleus to work harder.
- Focus your pressure through the big toe during the upward phase to ensure maximum engagement of the medial calf fibers.
Make it harder
- Incorporate '1-and-1/4' reps by performing a full rep, lowering halfway, returning to the top, and then performing a full eccentric.
- Slow the eccentric (lowering) phase to 5 seconds to maximize time under tension and muscle fiber recruitment.
