The size selection depends primarily on your hand size and training goals. The 60mm (Medium) is generally better for those with smaller hands or for focusing on higher-repetition endurance work, while the 70mm (Large) offers a thicker grip that is ideal for building significant crushing strength and simulating the demands of arm wrestling.

Yes, the device is specifically engineered to support both. You can perform standard symmetric wrist rolls for balanced forearm development or adjust your grip and leverage to target specific weaknesses or imbalances, which is particularly useful for combat sports like arm wrestling or martial arts.

The knurling is designed to be aggressive enough to maintain a secure hold even when your hands are sweaty. While chalk can always be used for extra security during heavy sets, most users find the texture sufficient for standard training sessions.

The straps are constructed from high-strength, industrial-grade nylon designed to withstand the friction and tension of repeated, rigorous workouts. They are built to handle the weight loads typical for forearm and wrist isolation exercises without fraying or snapping.

Absolutely. Weighing just over 21 ounces and featuring a compact design, it fits easily into most gym bags. It is a practical, grab-and-go tool for adding targeted forearm work to your routine anywhere you have a place to anchor it.
