Anatomi otot perut · 4 lapisan DARI DALAM KE LUAR 1. TRANSVERSE ABDOMINIS (paling dalam) - Wrap around badan kayak corset - Function: stabilize spine, deep core support - YANG PALING PENTING BUAT TULANG PUNGGUNG BAWAH 2. INTERNAL OBLIQUES - Rotation dan lateral flexion 3. EXTERNAL OBLIQUES - Opposite direction rotation 4. RECTUS ABDOMINIS (paling luar) - Six-pack muscle - Function: flexion (bending forward) - Yang biasa dilatih di sit

Biomekanik hypermobility di cewek 3 STRUKTUR TUBUH YANG BIKIN CEWEK LEBIH LENTUR 1. LIGAMENT LAXITY tinggi · genetik + hormon (estrogen, relaxin) 2. RANGE OF MOTION lebih luas · joint capsule lebih loose 3. MUSCLE MASS lebih sedikit rata-rata · less passive stabilization Kombinasi = mudah masuk pose · tapi tanpa kontrol otot Long-term risk: ligamen kendor permanen, joint instability Kenapa "gampang" itu bahaya Risk 1 · Kelenturan Pasif Tanpa Kontrol Kamu bisa masuk po

The biomechanics 3 ROOT CAUSES OF LOWER BACK PAIN 1. HIP FLEXOR OVER-TIGHT: Sit 8 jam sehari · psoas lock Setiap forward fold atau backbend · lower back yang bayar 2. GLUTE INHIBITION: Sitting culture bikin glute mati (reciprocal inhibition) Lower back extensors take over glute function Fatigue = pain 3. INTRA-ABDOMINAL PRESSURE (IAP): Diaphragm + pelvic floor + transverse abdominis Harus fire bersamaan buat stability Kalau uncoordinated · lower back compensate

The biomechanics FLEXIBILITY vs STRENGTH REALITY 1. LIGAMENT LAXITY: Ligament yang loose = joint stability berkurang Range of motion tinggi tanpa muscle control = risky 2. PASSIVE vs ACTIVE FLEXIBILITY: Passive: bisa masuk pose extreme dengan bantuan gravity/prop Active: bisa masuk pose extreme tanpa bantuan, dengan strength Yang healthy = active flexibility 3. HYPERMOBILITY SPECTRUM: ~15% populasi (higher in females + Asian descent) Bukan berka

The biomechanics DIAPHRAGM ANATOMY + FUNCTION DIAPHRAGM: Otot di bawah paru, bentuk kayak parachute Fungsi: Waktu contract (turun), paru mengembang, inhale Waktu relax (naik), paru kompres, exhale PROBLEM UMUM: Thoracic breathing dominance Dada naik-turun, diaphragm gak turun full Hasilnya: shallow breath, less oxygen, less core stability GOAL: 360° expansion (front, sides, back) Bukan cuma perut naik-turun (bad habit dari belly breathing) The 3 drills Drill 1 ·

The deeper anatomy ADVANCED FEMALE-SPECIFIC ANATOMY 1. LINEA ALBA (jaringan connective tengah perut) Cewek statistically lebih tipis Peran: transfer load dari core ke pelvis Diastasis: 2+ finger gap = kelemahan integritas 2. PELVIC FLOOR (bukan cuma organ container) 3 lapisan: superficial, urogenital diaphragm, pelvic diaphragm Peran core stability: coordinate dengan diaphragm dan transverse Fungsional: postural support + intra-abdominal pressure r

The biomechanics 3 FEMALE-SPECIFIC FACTORS 1. LINEA ALBA: Jaringan connective di tengah perut, cewek lebih tipis Efek: transfer of load dari core ke lower back lebih gampang bocor 2. PELVIC FLOOR: Bukan cuma organ container, tapi bagian dari core stability Kalau gak diaktifin, lower back yang ngambil beban 3. GLUTE CLENCHING PATTERN: Cewek default clench glute untuk ngerasain aktif Harusnya: lift pelvic floor dulu, baru engage core The 3 drills Drill 1 · P
