About This

  • Larger Spinner for Larger Hands - Built to be larger than the normal NSD series Spinner to accommodate larger hands. It's roughly the size of a softball to improve your grip.
  • Built for Power – This forearm exerciser is larger and heavier than plastic models—ideal for big palms and advanced users. The metal shell adds heft for serious grip strength training. Just wind the wheel, release, and rotate to activate this hand strengthener.
  • Track Your Power – This auto-start torque ball hand exerciser features a built-in speedometer to monitor your RPMs. Just wind the wheel, release, and rotate your wrist to spin past 15,000 RPM and build serious grip strength—no string or battery needed.
  • Spring-Loaded, Auto-Start Power – Wind the wheel, release, and rotate your wrist. This torqueball hand excerciser uses just thumb push to launch over 15,000 RPM and 26.8 lbs resistance. No batteries or strings—just gyroscopic force for beginner-friendly grip strength.
  • Designed for Active Hand & Wrist Training - This is a performance-based forearm excerciser & gyroscopic wrist strength trainer that requires real hand and wrist engagement to operate. Ideal for athletes, musicians, climbers, and rehab users with basic grip strength.
  • Stop Control – The Spring-Loaded Auto-Start feature allows you to stop instantly by just reversing the rotor which ensures smooth transitions between sets, making it a top choice for arm strength trainers & forearm exercisers looking for full control during workout.
  • Smooth, Stable Performance – Unlike alternatives, this gyro ball spinner is built with military-grade plastic, Zinc Rotor & stainless steel axle for rock-solid balance. No rattles, no vibrations—just consistent resistance for forearm workout.
  • Recouperating Precision – Designed as a forearm exerciser and finger strengthener, it supports wrist rebuilding, promotes blood flow, and eases stiffness. A smart choice for those recovering from repetitive strain or injury.
  • Disclaimer: Not a Passive or Automatic Device - Requires manual starting and wrist motion to generate resistance. Users with limited grip strength or wrist injuries may prefer our Electric-Start models.

    I’ve been lifting for a few years now and these straps made a noticeable difference. My grip doesn’t give out as fast on heavy deadlifts, and they feel really solid. Definitely worth it.

    The wrist wraps are actually better than I expected. Good support without feeling too stiff. Been using them for bench and overhead press, and they help a lot with stability.

    Tried a few different brands before, but Gripra gear feels more reliable. The quality is clean and simple, nothing flashy but it gets the job done. Shipping was pretty quick too.

    I like that everything feels made for real workouts. The grip pads especially help on pull days when my hands start slipping. Small upgrade but makes a big difference.
