Bear Plank Floating March

  • Compound
  • Timed hold
  • Lower legs
  • Shoulders
  • Upper legs
  • Waist

The Bear Plank Floating March is a dynamic core stability exercise that builds total-body tension and anti-rotational strength by challenging the kinetic chain in a quadruped position. It effectively targets the deep abdominals and stabilizers while taxing the shoulders, quads, and glutes through isometric and unilateral loading.

Setup

  1. Start on all fours in a quadruped position with hands directly under your shoulders and knees directly under your hips.
  2. Tuck your toes and engage your core to lift your knees 1-2 inches off the floor, maintaining a flat 'tabletop' back.
  3. Distribute your weight evenly between your palms and the balls of your feet, keeping your gaze slightly ahead of your hands.

How to do it

  1. Exhale and slowly lift one foot 2-3 inches off the ground while keeping the knee bent at a 90-degree angle.
  2. Hold the lifted position for one second, focusing on keeping your hips perfectly level and parallel to the floor.
  3. Inhale as you slowly lower the foot back to the starting hovering position with control.
  4. Alternate sides for the desired number of repetitions, maintaining a slow and steady tempo to maximize time under tension.

Form checklist

  • Keep knees hovering consistently 1-2 inches off the floor; do not let them rise as you fatigue.
  • Maintain a neutral spine from head to tailbone, avoiding any arching or rounding of the back.
  • Minimize hip shifting or swaying side-to-side as you transition weight between legs.
  • Keep your shoulders pushed away from your ears and actively press through the floor to stabilize the scapulae.

Pro tips

  • Imagine a glass of water resting on your lower back; your goal is to march without spilling a single drop.
  • Focus on 'bracing' your midsection as if someone is about to poke your stomach to engage the deep transverse abdominis.
  • Squeeze the glute of the lifting leg slightly at the top of the march to increase posterior chain activation.

Make it harder

  • Perform a contralateral march by lifting the opposite hand and foot simultaneously while maintaining a stable torso.
  • Increase the isometric demand by holding the lifted foot position for 3-5 seconds per rep.
