K9 Fit Club
More than a decade ago, K9 Fit Club founder Tricia Montgomery admitted it to herself: She and her dog were both overweight. They set out to lose weight together, and after dropping more than 130 pounds, Montgomery created K9 Fit Club to share her success with others. The curriculum is focused on joint dog-and-owner workouts—the core classes include games of fetch, obstacle courses, and cardio exercises, and others cover tai chi and dancing. The success of Montgomery's program has captured the attention of The Biggest Loser producer David Broome, who will bring Montgomery's program to reality TV in 2014.
