FITNESS teacher Colin Dobson doesn't expect his clients to wear expensive gym wear - in fact he doesn't expect them to wear anything at all.
Colin teaches fitness classes for naturists and he does it naked.
Colin, 42, explains: "I coach more than 25 clients from all walks of life, in their own homes, outdoors, or at my gym and private studio in Barnsley.
"I also teach a thriving online naturist community via Skype and Yahoo."
He started doing a naked fitness class for charity and raised £12,000.
