Handmaster Plus – A Vital Tennis Grip Training Exercise
Tennis Is A Classic Repetitive Grip Sport
‘9 muscles open the hand
9 muscles close the hand’
Repetitive grip imbalances are common for most athletes, especially in grip-dependent sports like golf and tennis. Repetitive gripping creates muscle imbalances that rob tennis players of their performance & health potential, but the tennis marketplace is mostly unaware of how – or even that – grip imbalance injuries develop. Grip muscles are often trained towards imbalance using ‘grip-only’ exercise devices by unknowing tennis athletes.
Handmaster Plus was designed by a doctor & former professional golfer to remedy this problem and properly strengthen and balance all 18 hand muscles. Dr. Zachary discovered the importance of the key grip stabilizer muscles on the back of the hand, wrist & elbow. Dr. Zachary knew these muscles were untrained in golfers, causing weakness, imbalance & injury. The result is maximum strength, performance, stability & circulation to the fingers, thumb, hand, wrist, carpal tunnel, forearm & elbow.
RSI’s (Repetitive Strain Injuries) Occur When Tennis Players (& Other
Grip Athletes) Chronically Repetitive Grip Without Opposition
- Carpal tunnel collapse – due to shortened, unopposed finger/thumb flexor muscles
- Tennis elbow inflammation – finger extensor muscles become inflexible
- Golfer’s elbow inflammation – finger & wrist flexor muscles shortened
- Wrist inflammation – finger extensor tendons & wrist ligament RSI
- Forearm muscles chronically shorten creating RSI potential
- Poor blood flow – small range of motion (ROM) limits circulation response
Common RSI Grip Injuries in Tennis
- Carpal tunnel syndrome, cubital tunnel syndrome
- Tennis elbow (lateral epicondylitis) & golfer’s elbow (medial epicondylitis)
- Thumb, small finger & wrist tendonitis and chronic fibrosis/adhesion
- Unhealthy muscles, tendons & cartilage are easily injured under stress (increased play or practice, high rough, root contact, cold conditions, etc)
Don’t Just ‘Squeeze Something’… Use Handmaster Plus – Why?
‘When I was on tour, most professional golfers just squeezed something as their grip training, whether a racquetball or a spring-loaded or coiled grip-only device. I knew it was causing imbalance and performance problems. I woke up a lot of golf pros.’
– Health professional & former professional golfer, Dr. Terry Zachary
All hand muscles participate during every tennis shot. The finger flexor muscles flex in grip, while the extensor muscles contract statically in support of grip. Thus, all 18 hand muscles are used & MUST be trained through full ranges of motion (ROM) to maintain health & performance.
Handmaster Plus easily strengthens and balances all 18 hand muscles… One continuous exercise allows tennis players to easily strengthen and balance the 9 muscles that CLOSE the hand, AS WELL AS the 9 muscles that OPEN the hand… resulting in strong stable hands, wrists, carpal tunnels, forearms, and elbows. Just minutes per day means better performance and a reduced risk of RSI injury from repetitive gripping.
