A simple exercise, but one of the best for core strength, posture, and stability. The plank engages your abs, back, and shoulders all at once—no equipment needed. 📅 Quick Wins - Start with 20–30 seconds, then build up over time - Keep your back flat and hips level (no sagging!) - Squeeze your glutes and brace your abs for full engagement - For variety, try side planks or plank shoulder taps ⚡ Why It Matters Strong core = better balance, improved posture, and less risk of injury in other movements (like squats or push-ups). ✅ What’s Next?
