KIESER EXERCISE MACHINE

Pronation and supination in the ankle joint

This exercise machine allows you to strengthen the muscles around the lower ankle joint axis in a targeted way – particularly the fibular muscles and the deep toe flexors. This improves your muscular stability, helps control rearfoot motion, and promotes a healthy roll-through motion of the foot – essential for stable walking, standing, and running. Through increased muscular pre-tension and improved activation, you’ll be able to control your foot more efficiently during the stance phase. This can significantly reduce the risk of ankle sprains. Even if you’re already experiencing ankle joint issues, this training supports your recovery and reduces the severity of injuries. 

Exceptionally precise

Strong step by step – strengthen your ankle joint in a targeted and effective way

Your feet perform precise work with every step – especially in the ankle joints. They carry multiple times your body weight and absorb forces during each step, change of direction, or jump. Sports like football, tennis, or volleyball place significant strain on your ankle joints – and make them particularly prone to injury. Targeted training improves control and load tolerance of your ankle joints – helping prevent injuries. 

Your advantages with the KIESER B3/4 – targeted for your ankle joint

Comfortable and ergonomic training position

Individually adjustable

Safe and controlled

Measurable strength progress

Training for the ankle joint

More stability. Fewer sprains.

The B3 specifically trains the anterior tibial muscle, the long toe extensors, and the fibular muscles – known as pronators, which lift the outer edge of the foot. The B4 strengthens the supinators: primarily the posterior tibial muscle and the long toe flexors, which lift the inner edge of the foot. Through targeted strength training on these machines, you noticeably improve the function of your foot muscles – and optimize the muscularly controlled roll-through motion while walking or running. The result: more stability, less risk of sprains – a highly effective contribution to injury prevention.

Targeted training of your ankle joints

How to train your ankle joints

To effectively strengthen your ankle joint muscles, the movement must be controlled and free from compensating muscle groups. The key is the precise guidance of the foot in inward and outward rotation of the ankle joint.

This is exactly what our special B3/4 ankle joint machine enables: With individually adjustable pads and adaptable axis guidance, you train in a targeted and safe manner – without unwanted compensatory movements. 

Train your ankle joints with the B3/4

For effective ankle joint training, controlled rotation without compensatory movements or activated accessory muscles is crucial. This makes targeted ankle joint training not only precise and effective – but also comfortable and easily accessible.
