You can’t spot reduce - you need to be in a calorie deficit and then it will start to diminish
This. Then all over exercise to help you tone all over - Pump might help. You need to use your abs to brace for squats & lunges, for example.
How is your everyday posture? Most people have bad posture, and it contributes to looking stout around the middle.
Try this simple exercise:
stand with feet hip width apart
put your index fingers on the point of your pelvis (hip bone - I think it's called the iliac crest?)
put your thumbs on the bottom of your ribs.
WITHOUT lifting your shoulders, try to lengthen the distance between your hips and your ribs.
You'll get the sense of how you need to lengthen your spine, by using your abs.
Also as you do this, think of your shoulder blades (scapulae) sliding down your back, but keep your ribs from flaring - think up, up, up, with your neck & spine, from your pelvis upwards.
Release by doing a slow roll down:
Chin to chest, then as you breathe out, try to curl your spine forwards, vertebra by vertebra. Soften/bend your knees as necessary so you're not pulling on your hamstrings. At the bottom, think of sending your sit bones (back of your hips) up to the ceiling.
Breathe in, then on an outward breath, roll back up, using your abs to suck yourself up.
You'd be surprised how much difference just improving posture can help - it requires you to engage your abs/core.
