Are you ready to mix up your martial arts moves? 3-2-1 Kick! is an interval kickboxing class that integrates cardio, strength and core work. In each round of the work phase, innovative cardio kickboxing combinations, martial arts-inspired strength work, and core moves are performed in quick intervals to keep participants engaged, motivated and challenged.

3-2-1 Kick! Details

Goal/Emphasis: total-body kickboxing interval training workout

Time: approximately 45 minutes

Equipment: dumbbells, stability balls and mats

Music: 136-150 beats per minute

Additional notes: Emphasize safety and technique, as punching and kicking involve quick extension and flexion of the elbow, hip and knee joints . Address the following:

  • When throwing punches and kicks, avoid fully extending the joint. Keep elbows and knees slightly bent to prevent hyperextension.
  • Rechamber punches and kicks.
  • Lift the heel to allow hips to rotate while punching. Power is generated from the hips.
  • Emphasize technique and control instead of height for all kicks.

Warm-Up (5-8 minutes)

Begin with standard warm-up movements to elevate heart rate. Gradually progress to basic punches and kicks. Warm-up may include side steps, hamstring curls, knee lifts, light kicks and bob-and-weaves. Review the following:

  • Jab: Straight punch extends from lead hand.
  • Cross: Straight punch extends from back hand (back heel lifts).
  • Hook: Punch comes across face, arm parallel to floor, elbow bent at 90o.
  • Upper cut: Back elbow stays close to body as arm scoops and extends upward, aiming under chin.
  • Elbow: Lower portion of forearm strikes across body, hand at chest.
  • Palm strike: Heel of hand aims front as arm extends.
  • Front kick: With hips facing forward, one leg lifts, knee bent at 90o. Leg extends, aiming with ball of foot. Leg rechambers and returns to original position.
  • Side kick: Knee lifts to chest, heel, hip and shoulder in one straight line. Base foot pivots so that toes point away from kick. Heel thrusts to side, toes down and pulled back. Knee rechambers, and foot returns to floor.
  • Back kick: Knee is lifted, and heel extends back, toes pointing down. Knee rechambers, and foot returns to floor.

Work Phase (30-35 minutes)

Each 6-minute round includes three parts:

  • cardio combination (3 minutes)
  • strength work (2 minutes)
  • core move (1 minute)
