Powerball | Golf Monthly
Turned up yesterday.
Fraction smaller than a tennis ball. This one's got a little LCD on the top for monitoring things like peak revs., total revs. etc.
Comes with a mini cd which ive managed to jam into the front of my laptop - nice one Bill.
Struggled to get it going to start with. It's supplied with a wrist strap and some little red bits of string. You need the string to get it going. This is done by inserting one end into a small aperture in the ball and winding it in like you would with a yo-yo. Once 'primed' it needs quite an abrupt yank to get it spinning. From there it's up to you to generate the required action to keep it going and speed it up as required.
The faster you spin the greater the gyroscopic force/torque and the harder it is to hang onto.
Takes a bit of practice but ive got the knack in less than a day.
I'm mainly using my dominant hand(right) until I see a physio on Monday and get the all clear that it's not contra-indicated for my left hand injury.
As far as muscle strengthening I can say that it seems to generate quite a 'burn' in the inner forearm (Brachioradialis) and front (anterior) deltoid*
Fun - yes
Addictive - certainly
Glad I got it - yes

I can't recommend highly enough. An absolute classic for anyone interested in gym work and targeted muscle fitness training.
