It is no secret that high intensity interval training (HIIT) is the big thing. More and more gyms are launching HIIT protocols to attract new members and appeal to the younger demographic.

HIIT has stripped away the intensity and group segment from a lot of mainstream mid-tier clubs with members migrating to training-specific studio concepts. HIIT really caters to the specific needs of this very fitness conscious group - it is not necessarily your mom's workout, but it is seriously tough, but fun, workouts for club members.
