Every session is tracked automatically on your own personal, data-rich website. Check in anytime from any of your devices.



The Science Behind Koko

"Is 30 minutes of strength training & 15 minutes of cardio really enough?"

We've been asked this question many times but the science is clear: quality beats quantity!

Many people have been conditioned to believe that "real" exercise means spending hours in the gym each day, or burning lots of joint-punishing time on the road or treadmill.

While this might still be required for the pro athlete or competitive bodybuilder, the rest of us can lose weight, burn fat, build muscle and be incredibly healthy with a lot less exercise using the latest scientific insights and a little bit of technology.
