Not Sure How to Train Your Forearms?
Here’s My Wrist Training Guide.
Solid Aluminium Build With a Thick Grip Presence
The first thing I noticed when I picked up this J Bryant handle was the sheer thickness of it. At 7.5cm in diameter, it immediately forces your hand open wider than a standard grip attachment. If your goal is to improve your grip and build serious forearm strength, that thickness alone changes everything.
It feels substantial, almost industrial, thanks to the aluminium construction. At just under 1kg, it has a reassuring weight that screams durability.
When I threaded the strap through one of the four holes and attached it to a loading pin, the setup was simple. The textured surface felt secure in my palm, and I could tell right away this wasn’t a basic plastic attachment. On my first pull, I felt immediate engagement in my fingers and wrist stability muscles.
The thick diameter demands progressive resistance because your hand can’t fully wrap around it. That means more activation, especially in the deeper finger flexors. It’s compact enough to throw in a gym bag, but serious enough to feel like a specialist arm wrestling tool.
The thick handle instantly sets itself apart from standard rolling grips, delivering both durability and precision in wrist and forearm targeting. For anyone seeking focused forearm development, it’s an industrial-grade tool that forces real engagement from the very first rep.

🧠 Performance & Feel During Training
Aggressive Finger Engagement with Constant Tension
Training with this handle feels intense from the first rep. Because of the thick diameter, your fingers never fully close, which creates constant tension across the hand. When performing wrist curls or containment holds, the resistance feels direct and unforgiving. The textured surface grips well, even when hands start sweating.
Using different strap positions noticeably changes how tension is distributed across the fingers. When positioned toward the outer fingers, I felt greater stress on top-roll mechanics. Centered positioning allowed more balanced wrist flexion work.
The mechanical feedback is immediate; if your wrist collapses, you feel it instantly. Over time, I noticed improved forearm endurance and stronger wrist alignment under load.
🏥 Rehabilitation & Injury Prevention Potential
Controlled Loading for Tendon Strengthening
When used with light plates and a slow tempo, this handle can support tendon conditioning and gradual forearm rehab. Because the grip remains open, it strengthens the deep flexor tendons that are often undertrained. This is particularly helpful for those recovering from mild tendonitis or repetitive strain injuries.
The strap-secured design reduces the chance of sudden weight drops, allowing controlled eccentrics. However, users should inspect the strap wear regularly due to potential fraying from sharp hole edges.
For post-surgery or early rehab phases, sanding or smoothing the holes may improve longevity and safety. Used responsibly, it promotes progressive strengthening without overloading vulnerable joints.

🏠 Everyday Usability & Practicality
Compact Specialist Tool with Minimal Maintenance
Despite its aggressive training effect, this handle is compact and easy to store. It fits inside a gym bag and works with any loading pin or cable system. Maintenance is minimal, simply check the strap condition and wipe down the aluminium surface after use.
It operates quietly, making it suitable for home gyms or garage setups. Because it’s mechanical and plate-loaded, there are no springs or moving parts to wear out. The included spare strap adds peace of mind, though upgrading to a higher-grade strap could extend longevity.
For serious grip trainees, it integrates easily into weekly wrist-focused sessions.
✅ Final Verdict: Is Thick Grip Power Worth It?
Serious Tool for Serious Wrist Strength
After training with this handle, I can confidently say it’s built for people who genuinely want to improve grip strength and forearm endurance, not casual users. The thick diameter forces honest effort. It exposes weak fingers and unstable wrists quickly, which is exactly what you want if your goal is real progress.
Yes, the strap edges may need minor smoothing, but the aluminium construction itself is rock-solid. For arm wrestlers, strength athletes, or anyone chasing next-level wrist stability, this tool delivers focused, brutal efficiency.
If you have smaller hands or are brand new to grip training, it may feel overwhelming at first. But if you’re serious about building containment power and heavy wrist flexion strength, I believe it’s absolutely worth the investment.
