The 5 Belly-Fat Exercises Trainers Say Work Best After 40

Belly fat becomes stubborn after 40. Your metabolism slows, muscle mass naturally declines, and stress levels often rise. That mix makes it harder to shed fat around your waistline, no matter how disciplined you are. However, there is good news: the right exercises, performed consistently and with intention, can make a significant difference.
As a coach, I have seen countless clients in their 40s, 50s, and beyond try everything to lose belly fat, long runs, group classes, endless crunches, and even extreme diets. Most saw little to no progress until they changed their training approach. Real results came when we focused on movements that demand full-body effort, build strength, raise the heart rate, and reinforce proper movement patterns.
These five exercises have delivered the best outcomes for my clients who want to burn belly fat, feel stronger, and look leaner. They are not trendy or flashy. They are reliable, effective, and proven over time. Add them to your weekly plan and expect visible, lasting change.
5 Belly-Fat Exercises That Work Best After 40, Trainers Say
Walking Lunges with Rotation

One of my clients, in his early 50s, hated cardio but wanted to lose weight around his midsection. We started working kettlebell swings into his routine a few days a week—just short sets at the end of his workouts. He noticed within weeks that his pants fit better and his energy had increased significantly. Swings hit the core hard, build power, and ramp up calorie burn fast. It’s one of the few moves that makes people sweat and build muscle at the same time.
How to Do It:
- Stand with your feet shoulder-width apart and hold a kettlebell with both hands
- Hinge at the hips and lower the kettlebell between your legs
- Explode through your hips and swing the kettlebell up to chest height
- Let it swing back between your legs and repeat in a steady rhythm
Recommended Sets and Reps: Perform 4 sets of 20 reps. Rest 45 seconds between sets.
Walking Lunges with Rotation

I trained a woman in her mid-40s who had been doing crunches for years without seeing any difference in her waist. Once we swapped those out for walking lunges with rotation, things started to click. Her posture improved, her waist tightened, and she started enjoying her workouts again. This move works everything from your legs to your obliques, and it forces your body to move the way it does in everyday life.
How to Do It:
- Hold a medicine ball or a dumbbell at your chest
- Step forward into a lunge with your right leg
- As you lower, rotate your torso over your front leg
- Return to center, step forward with the other leg, and repeat
Recommended Sets and Reps: Perform 3 sets of 10 reps per leg. Rest 60 seconds between sets.
Renegade Rows

A former athlete I worked with was strong, but he was carrying more belly fat than he liked. Once we added renegade rows, it was a turning point. He told me it felt like “planks with purpose” because it challenged his core and arms without wasting time. It’s a move that hits your abs, shoulders, and back all at once. For fat loss and function, it checks every box.
How to Do It:
- Get into a high plank with a dumbbell in each hand
- Keep your feet slightly wider than shoulder-width for balance
- Row one dumbbell up to your side while keeping your hips level
- Lower it back down and repeat with the other arm
Recommended Sets and Reps: Perform 4 sets of 8 reps per side. Rest 45 to 60 seconds between sets.
Squat to Overhead Press

I had a client in his late 40s who barely had 30 minutes to train. He needed moves that gave him the most bang for his buck. The squat-to-press became his go-to. It lit up his legs, core, and shoulders in one move, leaving him feeling like he had done a full workout in just a few sets. It also helped him feel more capable in day-to-day tasks, such as lifting, carrying, and getting up off the floor.
How to Do It:
- Hold a dumbbell in each hand at shoulder height
- Lower into a full squat with your heels grounded
- Drive through your legs to stand and press the dumbbells overhead
- Lower the weights back to your shoulders and repeat
Recommended Sets and Reps: Perform 3 sets of 10 to 12 reps. Rest 60 seconds between sets.
Standing Cross-Body Mountain Climbers

One client in her 50s didn’t want to get on the ground but still wanted something that made her feel like she was working hard. We used standing cross-body climbers as a core finisher, and she fell in love with the movement. It was easy on her joints but tough enough to raise her heart rate and fire up her abs. It became her daily go-to because it felt simple but effective.
How to Do It:
- Stand tall with feet shoulder-width apart and hands raised in front
- Drive your right knee up across your body while reaching your left hand down
- Return to standing and switch sides
- Repeat in a fast, controlled rhythm
Recommended Sets and Reps: Perform 4 sets of 30 seconds on, 30 seconds off.
Final Thoughts
Belly fat does not respond to one magic move. It takes consistency, intensity, and brilliant exercise selection. These five movements check all the right boxes. They build lean muscle, raise your heart rate, and teach your body to move better.
If you train with purpose, push yourself through these movements, and pair them with proper nutrition, you will feel leaner, stronger, and more capable with each passing week. I have seen it happen over and over again, and now it’s your turn.
