I sit at a computer most of the day, so I'm trying out this hand-crank wrist trainer to give my arms a quick tune-up during breaks. I do it right at my desk while sitting down or standing up. The build feels solid. I grip the center handle, keep the little black dot facing away from me, and spin the ball—centripetal force does the rest. It keeps blood moving through my wrists, forearms, and shoulders, and it’s already toning that stubborn underarm area. This will not get you big. I can see it being useful for light shoulder rehab, too. I got 2 because I think it may help with coordination. Time will tell, but overall, I'm pleased with this product.
I severely broke my wrist where the hand and arm bones meet back in December 2024. My bones started to heal the bones in my wrist backwards and to the side. So I had to have surgery and have two plates and a pin in it to hold it in place. I'm in physical therapy now and when I saw this wrist ball I thought it might help me gain strength back in my wrist, and arm. When I got it I thought it might be too heavy for my wrist. So I gave it a try and I was surprised that it really wasn't that heavy at all. As I was using the wrist ball I found it actually was easy to use. Not only did this wrist ball help my wrist it was also exercising my arm as well. Which is great because I've lost a lot of strength in my whole arm from it being in a cast so long. The next day my muscles in my arm felt a little sore from using the wrist ball. I'll going to bring the wrist ball to my physical therapist to show her because she said she might order a couple for treatment by building back strength in other patients that need to strengthen their arm. I'm so glad that this worked out for me. I definitely would recommend this wrist ball to anyone I know that might need to strengthen their arm/wrist.

I got this for myself but everyone in my family finds this weirdly fun. Like a giant fidget spinner. This means that all of us tend to accidentally overdo it and then get sore later. But I can honestly tell you this is the first time in my life I've ever accidentally exercised too much, lol!!! So I think this is a winner. My husband and both teens enjoy it too. It's very smooth and satisfying to "play with" though it's a bit bumpy when you're first starting. But then you get it going and it feels like you could go forever. Until you realize your mistake and that you're going to be hurting tomorrow! It exercises muscles that are hard to get to because of the round and round action. And the pink color means no one has taken it off to their own bedroom. It's very quiet and doesn't have any need for assembly. It's held up well to hours of spinning now so I think it's really good quality. It does the job!

Good workout for arms, I was skeptical but yes, your arms will get worked with this spinning ball. I like how easy it is to use and that it can be used with either hand. Things that could be better: the ball bearings allowing this to spin could be smoother, and the grip bar where you hold could be a little longer. My hands are in the small/medium side and the grip is just big enough. Anyone with larger hands may find this difficult to use, especially because your knuckles would be rubbing against the inner part of the ring and that could get uncomfortable. Wearing thin workout gloves may alleviate this problem. Otherwise, this is an ingenious device that serves it’s purpose, but it could be better. I included pictures comparing my boyfriend’s hand (size xl) and my hand (size s/m) for comparison.
Easy to use, effective but may be too small for those with larger hands

Questo attrezzo aiuta a esercitare braccia/spalle/busto in spazi ridotti e senza troppe difficoltà. È facile da usare dopo che si fa l'abitudine, serve solamente una spinta iniziale per far entrare in rotazione la "palla" che agisce da peso. L'aggancio del peso allo strumento è abbastanza solido, per il momento non ho avuto problemi, ma per sicurezza starei lontano da ambienti con oggetti fragili nel caso fortuito in cui si stacchi improvvisamente.
Un meccanismo semplice e abbastanza sicuro per questo attrezzo particolare composto da una maniglia che alimenta con il movimento una ruota cui è agganciato un piccolo peso che con la rotazione aumenta la forza di trazione tendendo diversi muscoli delle braccia e delle spalle. Nel. Manuale, piuttosto sommario a dire il vero, sono riportati 5 esempi di esercizio possibili ma nulla rispetto a ripetizioni o tempo, lasciando a valutazioni personali. Sicuramente l’utilizzo è immediato e si può fare anche a casa avendo a disposizione un po’ di spazio e mettendosi sicuramente scostati da oggetti o persone. L’allenamento è consistente se fatto con costanza e la trazione sulle spalle è sensibile con l’esercizio specifico. Può fare parte di una dotazione soft di casa insieme ad esempio ad una corda, un tappetino e un paio di manubri leggeri. Può essere usato anche da bambini a partire dai 7-8 anni con un minimo di allenamento ad esempio per mia figlia che fa piscina sono utili in riscaldamento.
