Exercise guide

Weighted Hollow Body Hover

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

This advanced isometric hold builds extreme core stability and anterior chain strength by using a long lever arm and external weight. It forces the abdominals, obliques, and quads to work in unison to maintain a rigid, 'hollow' spine position.

Muscles worked

Primary

  • Abs
  • Deltoids
  • Obliques

Secondary

  • Erector spinae
  • Glutes
  • Hamstrings

Equipment

  • Medicine ball

Setup

  1. Lie flat on your back with your legs fully extended and feet together.
  2. Hold a medicine ball or weight plate with both hands, extending your arms straight back behind your head.
  3. Press your lower back firmly into the floor, ensuring there is no space between your spine and the mat.

How to do it

  1. Exhale and simultaneously lift your legs, head, and shoulder blades 6 to 12 inches off the floor.
  2. Keep your arms locked out with the weight positioned just above the floor, keeping your biceps aligned with your ears.
  3. Hold this 'banana' shape statically, taking shallow breaths while maintaining maximum abdominal tension.
  4. Lower your limbs and the weight back to the floor with control once the set duration is complete.

Form checklist

  • Keep the lower back glued to the floor; if it arches, raise your legs higher.
  • Lock your knees and point your toes to fully engage the quadriceps.
  • Keep your chin tucked slightly toward your chest to avoid neck strain.
  • Maintain straight arms to keep the deltoids under constant tension.

Pro tips

  • Think about pulling your belly button through the floor and 'knitting' your ribs down toward your hips to maximize muscle recruitment.
  • Squeeze your glutes and inner thighs together to create full-body irradiation, which increases overall stability.

Make it harder

  • Lower your legs and the weight to just one inch above the floor to maximize the lever length and difficulty.
  • Incorporate a 'Hollow Rock' by gently rocking back and forth on your lower back without breaking the rigid body shape.
