## What is Deep Core?

Your six-pack does nothing for your spine.

Most workouts train the outer core - the visible muscles that look strong but don't protect you. Deep Core trains the muscles underneath: the deep stabilisers that wrap your spine and pelvis like an internal corset. The ones missed by crunches, planks, and every conventional ab routine.

Just 5 minutes a day, completely hands-free.

HOW IT WORKS
Deep Core uses guided breathwork drills built on a simple principle: a forceful exhale creates the internal pressure that activates your deepest core muscles. The app coaches you through each breath - exhale, hold, inhale - with a calm voice, a clear timer, and gentle animations. Just follow along. No equipment, no floor mat required, no gym.

THE EXERCISES
• The Hour Glass - deep core activation through forced exhalation
• Toe Taps - TVA and hip-flexor control
• Glute Bridge - glutes and posterior chain
• Bird Dog - contralateral spine stability
• Beast - full-body deep core hold

THE SCIENCE
Deep Core targets the muscles research links to a pain-free, stable spine:
• Transverse Abdominis - your internal corset
• Pelvic Floor - co-activates to stabilise the pelvis
• Multifidus - deep spinal muscles; their weakness is one of the strongest predictors of chronic lower back pain
• Diaphragm - the breath that powers it all

Grounded in published research on spinal segmental stabilisation, and inspired by the "cat vomit" exercise from The 4-Hour Body.
