Machine of the Month - B7 Seated leg curl
Keep Your Hamstrings Strong with the B7
The B7, or seated leg curl, isolates and strengthens the hamstring muscles in the back of the thighs.
Although the B7 looks like one of the simpler machines at Kieser, it is often completed incorrectly. The hamstrings are activated when bending the knees and help to extend the hips. They also play a big part in everyday activities such as walking, standing up from a chair and lifting things off the ground. The hamstrings are one of the primary muscle groups activated during activities such as running, cycling or swimming.
Important Technique Points
- As the exercise gets more difficult, the muscle will struggle to contract fully under the load. Often the body will try to compensate though arching the back, creating a "false range". Ensure that your lower back does not come away from the backrest
- Ensure that your feet are relaxed and keep them straight. This guarantees that you are working the entire muscle group evenly
- Ensure you don't lift your knees or lose contact with the shin pad in the end position
If you would like to add the B7 to your training program, be sure to talk to an instructor.
