Keith Britton is a New Hampshire native originally from Sandown. After a long career on the road living between New York and Los Angeles, he returned home and found functional fitness in 2012 after making a commitment to change his life.

Later that year he decided to share his passion with the Lakes Region by opening the gym. From humble beginnings in a single car garage, the business was born in December of 2012 with one simple purpose; to make people a little better one day at time. Come join Keith and the rest of the Juggernaut community in our mission of Forging Positive Leadership.
