• HIIT

• Tabata

  Tabata is a precise interval format: 20 seconds of work at your maximum effort, then 10 seconds of rest, repeated eight times — four minutes in all.

• Circuit training

  Circuit training is a workout built from several stations, each with its own exercise.

• Step aerobics

  Step aerobics is a cardio class to music on a low platform called a step.

• Indoor cycling

  Indoor cycling is a group cardio class on stationary bikes.

• Kangoo Jumps

  Kangoo Jumps is a cardio class in special rebound boots: under each boot is a curved spring that works like a small trampoline.
