Get ready to fire up your abs and sculpt a strong, lean core with this bodyweight-only workout! Whether you're at home or in the gym, no equipment is needed to torch calories and define your midsection. This workout includes four targeted core movements performed in straight sets, each designed to hit different regions of your abdominal muscles. With consistent effort, you'll build strength, increase core stability, and enhance your functional movement—all while incinerating body fat. Let’s break down each exercise to help you get the most from every rep and set.

"Lying Bottoms Up" kicks off this core session. This movement focuses on the lower abs and helps improve pelvic control. Lying flat on your back, lift your hips off the floor by driving your feet upwards, squeezing the core at the top for maximum contraction. Be sure to control the descent to engage the core throughout the rep. Complete 4 sets of 15 reps.

Next, hit the sides of your core with "Alternate Oblique Crunches." This move targets the oblique muscles, helping to bolster rotational strength and define the waistline. Bring the opposite elbow to the knee as you twist, exhaling with each crunch. Aim for 4 sets of 15 reps per side, focusing on form over speed to maximize muscle engagement.

The classic "Floor Crunches" are the third exercise. These target the upper portion of your abdominal muscles. Keep your neck relaxed and chin away from your chest as you crunch. Use your core—not momentum—to lift your shoulder blades off the floor. Perform 4 sets of 15 reps and hold the contraction momentarily at the top of each rep for added intensity.

Finally, end this routine strong with the "Front Plank with a Twist." This exercise adds a rotational element to the traditional plank, engaging both the deep core stabilizers and oblique muscles. Begin in a forearm plank position and twist your hips side to side without letting them touch the floor. Stay tight through your core and glutes to protect your lower back. Go for 4 sets of 15 reps.

This routine is excellent for all fitness levels and can be completed in under 20 minutes. It strengthens the core without equipment and improves posture, stability, and overall athletic performance. Add this to your weekly rotation 2-3 times per week to start seeing results. Stay consistent, focus on controlled repetitions, and remember—abs are made in the kitchen, so pair this with a healthy diet for best results!
