The Jack Burpee is a high-intensity compound movement that integrates jumping jacks into the traditional burpee to maximize cardiovascular demand and full-body muscle recruitment. It specifically targets the core and shoulders through the plank jack phase while building explosive power in the lower body.

Equipment

Setup

  1. Stand with your feet hip-width apart, core engaged, and arms at your sides.
  2. Ensure you have enough space to jump your feet out both behind and to the sides.
  3. Maintain a neutral spine and keep your weight distributed through your mid-foot.

How to do it

  1. Squat down, place your hands firmly on the floor, and jump your feet back into a high plank position.
  2. Perform a plank jack by jumping your feet out wide and back together while keeping your hips level.
  3. Jump your feet forward toward your hands, then explode upward into a jumping jack, swinging your arms overhead as your feet jump out.
  4. Land softly with your feet back together and immediately transition into the next rep; inhale on the way down and exhale on the jump.

Form checklist

  • Keep your hips level and core braced during the plank jack to avoid lower back arching.
  • Land softly on the balls of your feet to minimize joint impact.
  • Keep your hands stacked directly under your shoulders when in the plank position.
  • Maintain a proud chest and neutral spine during the squat transitions.

Pro tips

  • Focus on the 'snap' of the plank jack; the faster your feet move, the more your core must stabilize.
  • Minimize the time your hands are on the floor to keep the intensity high and the movement fluid.

Make it harder

  • Incorporate a full push-up immediately following the plank jack to increase pectoral and tricep activation.
  • Replace the standard jumping jack at the finish with a 'Star Jump' for maximum power output and heart rate elevation.
