I thought that the discomfort I feel in my right thumb after Body Pump would go after I had got more experienced, but it is the same every week. It is particularly linked to the parts of the class where you hold a plate in your hand with your thumb through the hole. My research says it is tendonitis. I looked for some sort of lightweight gloves or a support for my thumb on line today but there are so many out there and most have lots of good reviews and a fair few saying they are rubbish. Has anyone else had this problem and found a solution?
