Powerball
As recommended by Senior Golf Pro Karl Woodward (the current official Guinness Golf Drive World Record Holder, with a drive of an astonishing 408 yards!), Powerball is an amazing little exercise device that can help build strength and increase the length and power of a golfers drive.
Simply start the Powerball in your hand and keep it spinning by rotating your wrist. The faster you spin, the more demanding it becomes. At low speeds it can provide soothing, non impact rehabilitation, but spin it up to 15,000rpm and it will exert almost 40lbs of pressure on your limbs from just pure gyroscopic power.
The Powerball features a digital speedmeter/counter, which can be used to monitor daily increases in strength or for challenging friends for a top score. They are great fun to use and can be seriously addictive!
They look great, they are useful and they are good fun, making them an ideal inexpensive gift for any golfer.
