Your feedback
We looked at all of the hand strengthening products on the market and this (Handmaster Plus) was by far the best.
Dr. Sandy MacLeod
Repetitive flexion imbalances and injuries are an inherent part of our sport. Dr. Zachary gives us a magnificent solution to this problem with the Handmaster Plus. It is super-effective and so easy to incorporate into my training.
ROSS “ROSCO” HALCRO
I’ve struggled with symptoms of tendonitis for years while touring and was looking for the solution in all kinds of hand strengtheners. I found that all of them made my condition worse, and for a guitarist, this is a career killer. After stumbling upon the Handmaster Plus, I can truly say that it is the best product for prevention and treatment of tendonitis. My symptoms were gone after only ONE WEEK of use and I’ve never had a problem since.

The Handmaster Plus hand therapy device is simple to use, easy to explain and affordable to anyone. My patients love it. They take it home with them…and they actually use it! I recommend it to everyone to keep their hands, wrists, carpal tunnels and elbows balanced, healthy and feeling great.

Strong and balanced hands and wrists provide a huge performance advantage to hockey players of any level. The Handmaster Plus hand strengthening device is the most complete and effective hand exercise product that I have ever used.

The Handmaster Plus hand strengthening device is an essential piece of apparatus. It universally addresses the intrinsic muscles of the hand, wrist, forearm and elbow. It is a valuable tool for any physiotherapy practice.

My hands are my business. I have not seen a better product for complete hand strengthening than Handmaster Plus. I have noticed a great improvement in my hand strength and stamina.
Darren Griff
The risk of personal injury is always a concern to the musician. In my experience, using Handmaster Plus has reduced the risk while improving muscle control. In turn, muscle control has given me the important benefit of radically improving my speed, stretch and accuracy. I would strongly recommend Handmaster Plus to any musician seeking the ultimate performance.

My old wrist fracture had never healed properly. Since using the Handmaster Plus HHS, I can now move my hand and wrist through a full range of motion, which I have not been able to do since before I broke it
