Hand and Grip Strengthener – Grip Strength 101 – The Hand Muscles
Maximum hand & grip strength is dependent on 2 factors:
1) the strength and stability of the ‘grip-action’ muscle chain (the HAND CLOSING MUSCLES – i.e. the finger flexor & finger adductor muscles, located on the front of the hand, wrist & elbow) and,
2) the strength and stability of the ‘grip-stabilizer’ muscle chain (the HAND OPENING MUSCLES – i.e. the finger extensor & finger abductor muscles, located on the back of the hand, wrist & elbow).
In other words, the 9 muscles that ‘open’ the hand MUST BE strengthened and balanced along with the 9 muscles that ‘close’ the hand. Modern grip strengthener studies clearly illustrate that the ‘hand-opening muscles’ (grip stabilizers) act to ‘stabilize’ the ‘hand-closing muscles’ (grip action muscles) during all hand exercise & grip strength related activities. If you are neglecting to strengthen the hand opening muscles directly, you are limiting your grip strength, stability and performance at the fingers, thumb, hand, wrist, carpal tunnel, forearm and elbow.
Hand and grip strength is dependent on the strength of both the flexor muscles AND the extensor muscles. This is new technology that only we have researched to this degree.
Handmaster Plus strengthens all of the 18 hand muscles (9 grip action muscles AND 9 grip stabilizer muscles) using one convenient continuous hand & grip strength exercise – no need for multiple hand exercises or grip strength devices. Handmaster Plus combines 4 exercises into 1. No wasted effort. No segmented hand and grip strength routines.
