5 minutes a day. Science-backed breathing drills that activate the deep core muscles every regular workout misses — the ones that actually protect your spine. 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. BUILD THE HABIT Meet Beanie, your daily companion. Beanie lives on your home screen, tracks your streak, and celebrates every time you show up.
