Targeted Training for Upper Abs, Lower Abs, Obliques, and Stabilizers

This routine uses ten high-intensity movements to engage the entire abdominal wall. Consistency is key: perform this circuit 3–5 times a week to notice visible strength and posture improvements.

Upper Abs

1. Sit-Ups

Lift your upper body toward your knees. Control the descent to maximize time under tension.

3 SETS x 15 REPS

Directly overloads the rectus abdominis through a full range of motion.
Upper & Lower Abs

2. Raised Leg Crunches

Keep legs at a 90° angle. Crunch toward your toes while keeping the lower back flat on the mat.

3 SETS x 15 REPS

Lower Abs

3. Leg Raises

Lower Abs & Hips

4. Reverse Crunches

Resistance Training

9. Weighted Sit-Ups

Hold a dumbbell or heavy household item against your chest while performing sit-ups.

3 SETS x 15 REPS

Progressive overload leads to faster gains in core strength.
Deep Core & Posture

10. Forearm Plank

Plank - JEFIT

Hold a straight line from head to heels. Squeeze your glutes and pull your navel to your spine.

3 SETS x 60 SECONDS

Isometrically trains the “corset” muscles for a flat stomach.

⏱️ The 15-Minute Protocol

Rest 30 seconds between sets. Perform each move with high intention and slow control.

Pro-Tip: Abs are revealed through fat loss. Combine this routine with a balanced diet for maximum results!
