Complete Abs and Core Workout Plan You Can Do in 15 Minutes

This workout targets your upper abs, lower abs, obliques, and deep core muscles. It’s designed for people of all fitness levels, and best of all you can do it from the comfort of your home. No equipment. No excuses. Just 15 minutes of dedication a day.

Let’s dive in.

Why a 15-Minute Abs and Core Workout Plan Actually Works

Contrary to popular belief, you don’t need to spend hours doing crunches. Scientific studies, including research from ACE (American Council on Exercise), have shown that short, high-intensity core workouts performed consistently are more effective than long, low-intensity routines.

Fifteen minutes of concentrated, high-impact core exercises can increase endurance, improve posture, enhance athletic performance, and burn belly fat by triggering the afterburn effect (EPOC)—causing your body to burn calories even after you stop moving.

What Makes This Workout “Complete”?

This isn’t just crunches. A complete abs and core workout plan should hit every muscle group in your midsection. That includes:

• Rectus abdominis (your six-pack)

• Obliques (side abs)

• Transversus abdominis (deep stabilizing muscles)

• Lower back (for balance and support)

• Hip flexors and glutes (they play a major role in stability)

This plan gives attention to every area, ensuring balanced development and reducing risk of injury or muscular imbalances.

The 15-Minute Complete Abs and Core Workout Plan

Instructions:

• Perform each exercise for 40 seconds

• Rest 20 seconds between exercises

• Complete 2 rounds

• Total Time: 15 minutes

1. High Plank to Shoulder Tap
Targets: Core stabilization, shoulders, deep abs
Keep your body in a straight line, feet shoulder-width apart, tap each shoulder without rotating your hips.

2. Bicycle Crunches
Targets: Obliques, upper abs
Touch your opposite knee with the elbow while alternating sides. Keep the motion controlled, not rushed.

3. Leg Raises with Hip Lift
Targets: Lower abs
Raise your legs until vertical, then lift your hips off the floor. This burns the hard-to-reach lower belly fat area.

4. Russian Twists
Targets: Obliques, entire core
Twist your torso side to side while holding your core tight. Use a household item for resistance if needed.

5. Forearm Plank Hold
Targets: Entire core, back, shoulders
Engage your glutes and core, breathe steadily. Imagine pulling your belly button into your spine.

6. Flutter Kicks
Targets: Lower abs
Lie on your back, lift both legs slightly off the floor, and alternate kicks rapidly. Keep your core tight.

7. V-Sit Hold
Targets: Upper & lower abs, balance
Form a V with your torso and legs, hold the position while keeping your core engaged.

8. Side Plank (Each Side)
Targets: Obliques, stabilizers
Hold for 20 seconds per side in each round. Engage your core and glutes to stay aligned.

Pro Tip: Don’t skip the planks. They are incredibly underrated but extremely powerful for core engagement.
