I have slight arthritis in my hands?** A: I am no medic so please take what I say with a pinch of salt.The Gyro motion of the powerball is not too hectic and therefore should not cause damage to the arthritis. It might be too painful to turn your wrist to get the motion but if you can manage it I would think it would be excellent to get more movement going in the wrist. I suspect it would be worth giving it a go. **Q: Hi everyone :-) Please can anyone tell me if this device can be used as a workout for biceps?** A: It will hit your biceps a little bit, but not enormously so in my experience. It depends on the way you hold your arm when you are rotating it. Generally speaking I find it is very good as a wrist/forearm developer, it can get your triceps a bit more than biceps, but certainly not a primary exercise for the upper arm. Good for loosening/warming up. **Q: does it have a counter** A: As far as I'm aware, only the "Pro" Powerball series have a counter installed by default. I think you are able to buy a counter separately and install it in a "Regular" model though! **Q: how much does it way** A: Sorry about the delay but I have been away. It weighs 9.2 ozs, or 260 gms ## Customer Reviews ### ⭐⭐⭐⭐⭐ A great concept if it works and fun to use as an 80year old. *by on Reviewed in the United Kingdom 16 July 2025* As I've only had this for a couple of weeks, time will tell how effective it is. It seems well made and sturdy, comfortable in hand and you feel the Gyro as you work against it. It took me a good few attempts before suddenly I was successful, but longer with my other hand. Strange that as my dominant hand took longer to master it. I find it spins in both clockwise and anti direction too which you can change while it is spinning. The trick I find is to rotate smoothly as any jerky movements affect it spinning. I'm not sure if it is successful yet but I can feel the muscles after a few minutes use, they are aware of being used but not in a painful way. At the moment I use it around twice a day for around two minute seach hand. No doubt I will build this up for longer sessions in future. Please ensure you use the wrist loop though. I think if it got loose it could do some damage. I have not tried that but there is quite an energy build up as the Powerball rotates. I bought this to improve my grip and tone up my forearms etc. I am 80 yearsold and find my muscles not as firm as I would like. New update. A couple of weeks in and going well. I can feel a difference both in grip and firmness of forearms. I am up to 5 minutes each arm twice a day and can not only change direction of spin, but swap from one hand to the other and swap the wrist loop as wellwhile itspins. I am pleased with this product and will keep at it. I wonder if the "NO Pain No Gain" is necessary, as apart from a bit of tiredness and a not unpleasant feeling that Ihave used my muscles, there is no pain at all. I am happy about that as I am not a pain lover. ### ⭐⭐⭐⭐⭐ Great workout for the Arms etc. *by on Reviewed in the United Kingdom 15 April 2016* When you first open the packaging, You will see a Powerball and 2 pieces of red string- cord..1, At first, I thought the Powerball was a bit of waste of time. It took me a long time to get to grips with how you get the inner ball to rotate.Once you have the hang of it though, it's really quite easy to use.2, Place the small length of red cord into a hole and turn the inner ball a few turns, Then pull. It will start to spin slowly.The idea is you then turn your hand and slowly to keep it rotating. It is the inner ball which spins.Then the more you turn your hand the faster it will. And the harder you have to hold it, That is the idea of it.3, This is the original Powerball and I think the best, The manufacturer's description really doesn't do this product justice,Try the website. very helpful site.4, First use this Powerball at low speeds it is great for wrist and arms.At the high speeds it gives an Amazing workout and really builds up all the arm and shoulder muscles.That is If you can hold on to the ball, it is quite hard at full speed. I think it would benefit Racket plays etc.5, The build Quality is Excellent and there is a lifetime guarantee. I could write so much more about this product,If you want a great workout for arms wrist and shoulder, Will leaves your arms etc. burning after a few minutes.You've got to buy one and try for yourself, you will not regret it. This one has lasted me a long, And still works great.You could Try the version with a Timing computer on top of the Powerball so you can see how you're progressing.I would Highly recommended great workout. Well worth the money for a Quality Powerball. ### ⭐⭐⭐⭐ Basic Powerball *by on Reviewed in the United Kingdom 6 November 2009* If you've never seen on of these 'in the flesh', you might -like me- wonder what the difference is between this model and the one with the digital clock on top. I think that the clock one just allows you to see what speed you got up to and/or time your sessions. What I find when using the ball, though, is that it can be difficult to keep holding in exactly one position, and I think I would prefer the ordinary flat cap (the black bit in the pic with the nuclear fission-type logo) than one with a clock on. To be fair, though, I haven't tried one of those, so maybe you'd need to read their reviews to see if worth the extra money. I'm quite happy with the basic model, which is excellent value.What isn't really explained is that you have to start the ball with a thin cord, as you did with gyroscopes you may have come across when a child (it's basically a gyroscope in a clever housing). Once started, it is initially quite difficult to transfer to the palm of you hand, as you can only hold it in one position (to allow the wheel underneath to freely rotate). After a while you get the hang of it, and learn the action you need to speed up the rota, and start feeling the benefit of exercise. It's quite addictive, and easy to sit using while just watching TV.I'd absolutely recommend the easy-starter, Powerball Eezi Starter as it does away with the need to use the cord to start it (if you watch bike racing, the device works just the same as the motors they used to use to start up the bikes by spinning up the back wheels). It also makes a convenient place for the ball to sit when not in use. The leg strap, however, I found rubbish.
