Level 1: A moderately intense workout which we hope will make you break a sweat after about 10 minutes. You won't be out of breath, but you won't be able to sing a song during your workout either.

Level 2: A very challenging workout which should make you break a sweat within 3-5 minutes. Your breathing will be heavy to the point where you will be unable to speak in a complete and fluid sentence.

All: All levels.

  • HIIT

    Train like an athlete with a workout that alternates between intense bursts of activity and fixed periods of less-intense activity or rest.

    Calorie Crusher
