Customer review from the Amazon Vine Programme (What's this?)
I must admit I was rather sceptical about this product; however, now that I've used them my scepticism has gone.
A nice simple product - you slip them around the dumbbell or the barbell and you are ready to go. They have a noticeable effect on your workout; so much so that it is advisable to reduce the amount of weight you are lifting.
