Questions? We've got you!
Honestly, both. You can use it to bounce back from injury or push through plateaus. It’s great for light recovery days or full-strength training, depending on how you dial it in.
Just twist the knob. That’s it. More tension when you want a burn, less when you need to ease in. Super simple, but super effective.
No setup, no weird parts, no instructions you’ll ignore anyway. It’s ready to go the second you unbox it.
Absolutely. Whether you’re starting out, rehabbing, or already crushing heavy lifts, the Dynamo adjusts to you. One tool, any level.
Your whole forearm gets in on the action. The twisting motion hits both flexors and extensors—so your grip, wrists, and lower arms all get stronger together.
We made the grip thick enough to challenge strong hands, but smooth and comfy for smaller ones too (without slipping or straining).

I had been using ice, stretching, a splint, and an infrared light mitt for 3 months to help my left wrist and thumb. It was very painful. I did not stop working out, using a wrist wrap to help get through them.
I decided to try the dynamo to see if maybe that would help with recovery. After 2 sessions the pain was reduced. I use it every third day to help strengthen and heal the joint. It has been progressively improving with each session. I use it for about 5 minutes per session, with the 40/20 sec work/rest cycle.

I play and Coach Pickleball all day . I had an awful and persistent case of Tennis elbow . After using the Gripzilla the pain in my elbow completely went away .

I have been using the dynamo for about 3 weeks. Really there is no words to describe this thing. My forearms are on fire. A must purchase. My tennis elbow surgery is postponed.

My wrists are. wreck, so Ive got to keep them reasonably strong and flexible. I usually have a couple of implements that I use for that but it's a little bit of a pain to just take and use them during the day. No a huge deal but the Dynamo is wayyyy more likely to make it into my hands and get used. It's a tough one too. I can NOT dail it up all the way so there is a lot of room for growth. It's also made to withstand abuse. This is a real piece of gym equipment. Not cheaply made at all.

Thanks very much for sending me the two items that I purchased. I am quite pleased with the Dynamo – Grip Wrist and Forearm Strengthener and I am seeing immediate impact to my forearms.
