This hand grip strengthening kit includes 6 components:
Finger Strengthener

These finger strengtheners have been designed to strengthen the muscles of the hand and fingers.

1. Strengthens Grip Muscles: Hand grip exercisers target the muscles responsible for gripping and squeezing. These muscles include the flexor muscles of the fingers and the extensor muscles of the hand and forearm. 

2. Injury Prevention and Rehabilitation: Grip strength exercises with a hand grip exerciser can help prevent certain hand and wrist injuries, such as repetitive strain injuries (RSI) and carpal tunnel syndrome. These exercises can also aid in the rehabilitation of hand and finger injuries.

5. Benefits Sports Performance: Many sports require strong grip strength and forearm muscles. Athletes in activities like rock climbing, golf, tennis, martial arts, and weightlifting can benefit from incorporating grip strength exercises into their training routines.

8. Supports Hand Health: Strengthening the hand and finger muscles can improve joint stability and promote better circulation in the hands and wrists, which can contribute to hand health and comfort.

The different colours are different resistances.

As with any exercise, start with an appropriate level of resistance and gradually increase it as your strength improves. If you have any existing hand or wrist conditions, it's recommended to consult a healthcare professional before using a finger exerciser.
