Plank Jack

  • Begin in the plank position with your shoulders over your wrists, your body in one straight line, and your feet together. Pull your core toward your spine.
  • Jump your legs wide apart, similar to the motion of a jumping jack. Land softly, engaging your core throughout.
  • Jump your feet back together at center.
  • This counts as one rep. Complete for 10 reps.
