TERM: 3-Cycle System

DEFINITION: It’s a program used by Equinox that has been research-proven to improve strength, power, aerobic capacity, and lean body mass levels.

In Cycle 1, you master fundamental movement patterns and set a foundation for high-level training, says Matt Berenc, Beverly Hills-based director of the Equinox Fitness Training Institute. For example, a trainer might have a client perfect their bodyweight squat form before adding weight or moving on to squat thrusters.

Cycle 2 includes more stressful work. People might add more weight, up their volume, or incorporate more complex moves. Finally, Cycle 3 combines high-intensity training with skill-based exercises.
Here’s an example of what you might do in each cycle: In Cycle 1, you’d perform a half-kneeling ViPR chop with a focus on perfecting the movement. In Cycle 2, you would progress to the ViPR single-leg deadlift to balance, further honing the movement while adding intensity. And in Cycle 3, you would kick things into high gear with the kettlebell clean to overhead press.
