About Us

30/60/90 is HIIT training at its finest. It was created by fitness expert, Kristi Molinaro, and was named the "Best Fat-Burning Class" by New York Magazine shortly after setting the standard for modern group fitness.

30/60/90 has simple choreography. It is a scientifically combined series of cardio drills in a high intensity interval training format designed to get you (and keep you!) in the best shape of your life in just 38 minutes per workout!

Attracting women and men, newcomers and elite athletes, 30/60/90 took group fitness to a new level almost a decade ago and continues to set the bar for all HIIT training workouts around the globe.
