NSD Spinner Precision Made By Its Inventor Since 1992
NSD Spinner powerball hand grip exercise ball for strength training rehabilitation

Unleash Your Inner Power by this Innovative Gyro Exerciser

NSD Spinner is a gyro ball that has a mechanism allowing you to rotate your hand to increase the revolutions per minute (RPM) of the gyroscope itself. Our Spinners are a quick and effective way to increase your grip strength and an excellent complement to those who play sports. Professionals and amateurs alike can all benefit from our "one minute, one powerful hand" pledge!

NSD Spinner is small and portable. Put one at your desk. Put one in your gym bag. Take one with you anywhere, and you can spin your way to a healthy lifestyle ANYWHERE!

SPORTS

The wrist and the forearm are a vital part of your game. You must keep your wrist in perfect position at the point of contact. Without a strong wrist and forearm, you can't generate the force needed to power through a forehand stroke, and without a flexible and strong wrist, you can't transfer that force generated through your legs and hips and up through your elbow to whip the racquet through the ball on a serve.

By using the physics of a spinning gyroscope, angular momentum is generated in a small "ball" roughly the size of a tennis ball. Our Spinners are capable of spinning in excess of 15,000 RPM, and at that speed even a few ounces can feel like POUNDS. Trying to keep a spinning gyroscope at that speed steady requires significant strength of muscle around your wrist, and by training regularly with an NSD Spinner, you can achieve the control over your wrist required, as well as build up the strength in your forearm needed, to hit a winner across the net.

FITNESS

Break a sweat Anytime & Anywhere with the impressive NSD Essential Spinner. This hand-held wonder spins at up to 15,000-plus RPM and uses angular momentum to give your fingers, hands, wrists and forearms a sweat-inducing workout. Just a few minutes a day with the NSD Spinner can be equivalent to hours of full-motion work with a dumbbell or curl. It provides excellent strength-building benefits to athletes looking to hone their forearm and wrist strength. Plus, it’s really fun to operate! The compact, break-resistant design means you can toss it in your bag for strengthening on the go.

MUSICIANS

Regular use of the NSD Spinner will train the muscles in your forearms and wrists for fine motor control and coordination. With NSD Spinner, you may also increase dexterity while relieving stiffness and fatigue in the wrist, arms and shoulders. Eventually, boost endurance while improving your overall performance.

Because to spin the NSD Power Spinner at 10,000 RPM requires precise timing and fine movement. Using the NSD Power Spinner regularly will improve control over wrist and arm muscles for delicate tasks such as playing a guitar, keyboard or improve the fast twitch muscles in the forearms for a rip roaring set on the drums, or anything requiring surgical precision of your hand.

GAMING

NSD Spinner has also been an invaluable tool for many professional E-sports players. Fans of League of Legends, Dota 2, Counterstrike Global Offensive, and StarCraft alike have found the NSD Spinner to be highly beneficial before, between, and after games. Competitive gamers who practice endless hours place a huge strain on their wrists. Carpal tunnel, tendonitis, and repetitive stress injuries are common occurrences when you spend prolonged hours on the computer. By ensuring continuous growth in muscles and flexibility in the forearms and wrists, gamers see prolonged careers with stronger and quicker movements in their wrists. Players who use the NSD Spinner can see marked improvements in muscular strength, flexibility, and blood circulation of the forearm, hand, and wrists. Many of our players have also found improvements in micromanagement, reaction time, and reflexes. You are only one ‘flick’ of the wrist away from that game-changing play.

Tips on Operating your NSD Spinner

No battery required! Your hand is the battery of this device. The motion of your hand rotating the Spinner is similar to making ice cubes swirl inside a glass. The essence of operating the Spinner is not about how fast you rotate your wrist. It’s about how to synchronize your wrist rotation to the momentum and timing the rhythm of the rotor’s gyration. The faster the rotor spins, the easier it is to operate. Make sure you start the Spinner with sufficient speed.

Just like riding a bike! The faster you spin the wheels, the easier it is to stay up because the wheels actually start to fight to stay in their original upright position. This same principal is used in NSD Spinner to create force against your hand as you move it. At 10,000 RPM you can generate up to 26.8 lb-in of torque - with the Essential models.

Customers are mixed about the noise of the hand strengthener.

Overall, the noise is a mixed bag, and it'd be best to read the reviews carefully before making a purchase.

44 customers mention10 positive34 negative

Customers are dissatisfied with the rotation of the hand strengthener. They mention that the rotation can't really be sustained for longer than about a minute, the internal sphere no longer turns, and it's impossible to get enough rpm's generated to be effective with the foot long string. Customers also mention that it starts to vibrate and gets a lot louder during use.

"...The "ball" inside is a bit loose and rattles when you shake it. Also, I'm afraid to drop this one...." Read more

"...I guess that it's wearing out from constant use and it takes more force to spin. My wrists are also starting to ache again and fell very tired...." Read more

"...this as fitness equipment for a couple reasons: (1) The rotation can't really be sustained for longer than about a minute at max effort..." Read more

"...In addition, it has a fidget spinner appeal that makes me want to use it...." Read more

It really, REALLY WORKS!
5 Stars
It really, REALLY WORKS!
I bought mines during a lightning deal. I saw how many people were buying it and looked at the great ratings, so I said to myself "Heck, why not?" I ordered it. When it finally got my hands on it I gave it a few tries... I immediately thought about returning it since I couldn't keep it spinning for more than 10 seconds. I almost threw it to the side, but I decided to give it one more shot. All these glowing reviews you read here cannot be wrong! So I gave it another try.I freaked out a bit at how long I got it spinning using lots of action from my hand and wrist. I started rotating my wrist faster and in a tighter circle, the ball started to get louder and LOUDER. I originally thought NSD Power made up the claim of "26.8 lb-in of torque at 10,000 RPM." I spun it so fast that I started to lose my grip on this thing and it felt like it wanted to fly right out of my hand!It is a challenge to get it up and running at first. TIP: You do NOT have to pull really hard on the string to get it going. You need a good and smooth pull; you do not have to yank on the string. This is just to get it started. Once you start rolling your wrist and follow through with hand motions, you can get it to spin faster and faster.After a few minutes of using it, I can feel my forearms and wrist feel a bit tighter since it got that work out. Now I want to see if I can do the same with my left arm and try to swap the ball between hands while keeping it spinning.It is worth a buy!
