Koko FitClub, Acton

Koko FitClub’s automated personal-training system rockets both men and women toward fitness goals with 30-minute custom workouts that incorporate cardio and strength training. An initial consultation determines fitness levels and baseline measurements, which Koko’s computerized equipment uses to design a tailored workout plan that precisely measures the weight, pace, and rest time appropriate for each exerciser.

The Koko machines guide exercisers through each workout and adapt as the user’s fitness needs change in order to constantly challenge the body. Designed by professional trainers, workouts maximize the body’s lean-muscle mass, which can boost metabolism and help fight off disease by challenging viruses to kickboxing matches. Exercisers can track their shrinking waistlines and swelling muscles online by analyzing workout scores and comparing individual fitness levels to the Koko FitClub community.
