How to perform it
Isolation work is usually trained in a higher rep range: 2 to 4 sets of 10 to 15 reps with 45 to 90 seconds of rest, performed under control.
Execution and technique cues
- Sit in the machine, position the balls of your feet on the platform, and adjust the thigh pad securely.
- Release the safety bar, lower the heels under control, and maintain an upright posture.
- Push through the balls of the feet to raise the heels as high as possible.
- Hold the contraction briefly at the top before slowly lowering the heels into a deep stretch.
Common mistakes
- Bouncing the weight at the bottom of the movement using Achilles tendon elasticity.
- Using the hands on the thigh pads to push the weight up.
- Cutting the range of motion short at either the top or the bottom.
Frequently asked questions
- Why does this exercise target the soleus muscle more than the gastrocnemius?
- Bending the knees to 90 degrees slackens the gastrocnemius, placing the mechanical load primarily on the soleus.
- How long should the pause be at the bottom stretch?
- Pausing for 1 to 2 seconds at the bottom helps eliminate the stretch reflex and ensures the calf muscles do the work.
