The prisoner calf raise is a calf exercise that involves standing to lift the heels while placing the hands behind the head. This “prisoner” position automatically keeps the torso upright and puts extra emphasis on postural control during the ankle movement.
The exercise is performed without external weights, so the focus is entirely on controlled plantar flexion and muscle activation of the calf. This makes it an accessible yet effective exercise for both activation and strength endurance.
Aims to strengthen gastrocnemius and improve ankle stability. Supports running mechanics, jump release and postural control. Suitable for both basic strength development and preventive training.

The prisoner calf raise is used to improve calf strength and ankle stability with emphasis on postural control. The exercise is suitable as an activation exercise within warm-ups, but also as a basic strength endurance exercise within rehabilitation or preventive programmes.
In addition, this exercise is relevant for athletes who want to gradually build up their ankle load without external weights. Due to the low entry level, the exercise can be applied at different stages of training and recovery. 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 individual load capacity, symptoms and recovery status.
