We are unleashing these extreme fitness photos from author Mike Gillette, taken for his Rings of Power fitness book. Besides being an author, Mike is a former SWAT commander, paratrooper and executive bodyguard. Also featured here is the amazing Adrienne Harvey, who seems to have no limits to her talent. If your fitness routine is lacking a spark, or is boring you with repetition, try adding weights, or hanging upside down, using the Rings of Power style of fitness. It was a pleasure working with Mike and Adrienne, along with Dragon Door on this incredible photo shoot. Good luck team!
