The goal of Crossfit is to improve participants’ level of fitness.

Crossfit is a demanding workout program. Sessions are normally limited to intense 30-minute or less workouts that require all-out exertion on behalf of participants. Some of the movements common in Crossfit training include:

  • Sprinting

  • Jumping Rope
  • Box Jumps

Programs at Ox Box ® Gym include combinations of these movements and more to form “WODs,” or “Workouts of the Day.” Hour-long classes include the intense 30-minute WOD, a warm-up, a skill development session, and a group or individual stretch.
