Introduction
A strong core is the foundation of nearly every movement — from squatting and jumping to sitting and standing upright. But building true core strength goes far beyond just doing crunches.
In this article, you’ll get a simple, effective 15-minute daily routine that targets deep abdominal muscles, obliques, lower back, and overall core stability — no equipment required.
Why Core Strength Matters (More Than You Think)
The core includes your abs, obliques, transverse abdominis, erector spinae, and even your glutes. A strong core improves:
- ✅ Posture & spinal alignment
- ✅ Balance & stability
- ✅ Athletic performance
- ✅ Lower back protection
- ✅ Functional strength in everyday life
