I had considered Globe Gripz for awhile but was a little unsure. After looking at the information on the Sam’s site I decided to buy. The Globe’s arrived promptly and I have been using them for a month or so now. The product certainly is strange to use initially because of the ‘new’ hand position. At first I used less weight for exercises while I got used to them but I am now back up to usual amounts. Grip strength has increased, I really notice a difference with bicep Curls and tricep extensions. The globes change where the bar’s location in relation to the wrist… Positioning it further away from the joint. But arm exercises are substantially more comfortable! The only issue I’ve had is with the jokes about having ‘blue balls’ in the gym! Thanks to Sam’s fitness for carrying the product.
