Melt Belly Fat with This 30-Day Interval Walking & Strength Workout

These workouts will help you build muscle and endurance while inching closer to your weight-loss goals.
FACT CHECKED BY Alexa Mellardo

As a tenured performance coach, I've seen firsthand how combining strength training with cardio can help clients achieve their weight-loss goals. While you can't specifically target fat loss in one area—like the belly—with the right mix of exercises and a healthy diet, you can make significant strides toward a leaner, stronger body. So, I've curated the ultimate 30-day interval walking and strength workout for belly fat.

Strength training builds muscle, which increases your metabolism, while cardio, like interval walking, helps burn calories and improve cardiovascular health. This combination creates an ideal environment for fat loss.

This 30-day workout plan is designed with those principles in mind, blending strength days with walking intervals to challenge different energy systems, boost metabolism, and optimize fat burning. All you need are some basic pieces of equipment—dumbbells and a slam ball—and your commitment to the routine.

These workouts, which are effective for all fitness levels, will help you build muscle and endurance while inching closer to your weight-loss goals. Stick to the plan, and in 30 days, you'll feel stronger, fitter, and one step closer to melting away stubborn belly fat.

What To Expect with the Strength and Walking Workouts

Combining strength training and interval walking offers a balanced approach to fat loss and muscle toning. Each week, you'll perform three strength workouts targeting different muscle groups—upper body, lower body, and full body. These workouts incorporate multi-joint movements like squats, rows, and thrusters, which build muscle and keep your heart rate elevated, leading to a higher calorie burn.

On alternate days, you'll focus on interval walking, varying the intensity and duration of your walks to challenge your cardiovascular system. HIIT-style, long-timed, and distance-based intervals will boost your metabolism and burn fat efficiently. This blend of strength and cardio creates an optimal environment for fat loss while improving muscle definition and endurance.

How To Progress the Workouts Week to Week

To see consistent progress over the 30 days, gradually increase the intensity and volume of your strength and walking workouts. In the strength sessions, start with a moderate weight that challenges you but allows you to maintain good form. Aim to slightly increase the weight each week or add a few more reps to each set. By progressively overloading your muscles, you'll build strength and muscle tone.

You can increase the duration of the fast-paced sections or the workout's overall length for the walking intervals. For example, in Week 2, you might add an extra interval or extend your fast walking time from 1 to 1.5 minutes. By making these minor adjustments week by week, you'll avoid plateaus, continue to burn fat and improve fitness throughout the month.

  5. Ensure your back remains straight, and avoid twisting your torso.

  7. Avoid using momentum to lift the dumbbell. Focus on the muscles in your back to do the work.
  8. Repeat all reps on one side before switching.

2. Dumbbell Incline Bench Press

  1. Adjust a bench to a 30–45-degree incline.

  5. Keep your palms facing forward and maintain control of the weights.
  6. Lower the dumbbells slowly by bending your elbows, allowing the weights to come down just below chest level. Your elbows should stay at a 45-degree angle to your torso.
  7. Push the dumbbells back up to the starting position, focusing on using your chest muscles to press the weights.

  5. Continue alternating sides controlled, maintaining tension in your core throughout.
  6. Perform 10–15 reps per side, making sure to breathe evenly.

Notes:

  • Keep your lower back pressed into the floor to avoid arching and straining your spine.
