The Routine: Fast, Focused, and Functional

1. Plank to Shoulder Tap

How to Do It: Begin in a high plank. Tap your left shoulder with your right hand, then alternate. Keep hips steady.
Targets: Transverse abdominis, upper abs, and stabilizers.

Targets: Obliques, upper and lower abs.

💡 Keep the motion slow to really feel your core engage.

💡 Place hands under glutes for support if needed.

4. Toe Reach Crunches

How to Do It: Lie with legs extended straight up. Crunch up, reaching for your toes with both hands.

How to Do It: Sit with knees bent, heels slightly off the floor. Twist your torso side to side while clasping your hands together.
Targets: Obliques and deep core muscles.

💡 Add a water bottle or small weight for extra challenge.
