Hollow Body
Use Hollow Body for dynamic hollow-body rocks that challenge core tension while the body moves as one piece.
Overview
Hollow Body is an intermediate dynamic core drill on Flexor. It uses small hollow-body rocks to challenge body tension while the trunk stays braced.
What Hollow Body targets
It focuses on the core, shoulders, hips, and quads as the body moves as one connected shape.
Why add Hollow Body to your routine
Use it to build dynamic bracing and control before harder gymnastics, calisthenics, or strength work.
- Dynamic hollow-body rocks distinguish it from the static hold.
- Range can be scaled by bending the knees.
Who it is for
It suits movers who can keep the low back controlled during core work.
When to do it
Use it in core blocks or warm-ups for bodyweight training.
Hollow Body is a mobility exercise designed to improve comfortable range-of-motion in multiple areas. Work in a comfortable range and avoid sharp pain; slow, steady breathing helps you stay relaxed and controlled.
Setup cue
Lie on your back with arms overhead, legs long, and lower back gently pressed into the floor. Lift shoulders and heels into a hollow shape, then make small dynamic hollow-body rocks from shoulders to hips.
Practice notes
In Flexor, Hollow Body is typically prescribed as about 45 sec per round, 1 rep, and 1 set. Adjust the dosage to what feels sustainable, breathe steadily, and ease off if anything feels sharp or unsafe.
