Calf extension elasic in seat
Calf extension with elastic band in seat is an exercise in which you extend the ankle downward from a seated position against resistance from an elastic band. The movement is performed by moving the foot from a neutral position to plantarflexion, actively tightening the calf muscles.
By using an elastic band, the resistance is easy to dose and the exercise can be performed in a controlled way. This makes the exercise suitable for targeted activation and strength building of the calf muscles.

✓ Deliberately tighten the calf muscles
✓ Keep the lower leg stable

When this exercise?
Calf extension with elastic band in seat is used to improve strength and control of the calf muscles and ankle. The exercise is often used within rehabilitation programmes for ankle or Achilles tendon problems.
In addition, the exercise can help restore muscle strength and ankle stability after a period of reduced load. By adjusting the resistance of the elastic band, the exercise can easily be tailored to the level of the athlete. Application, loading and progression should always take place in consultation with a physiotherapist or other qualified professional to ensure that the exercise is safe and tailored to the individual's load capacity, symptoms and recovery status.
