If you keep a diet but it seems like that extra weight around your waist is in no hurry to leave or your abs aren’t as defined as you’d like them to be, it’s time to incorporate some simple but effective exercises into your workout. The pilates training system was created for spine rehabilitation but it also helps perfectly tone deep core muscles and boost metabolism.

Starting position: Lie on your side. Bend one arm and put it under your head. Place the other arm in front of you. Slightly bend your knees, keep your feet together, and squeeze the glutes.

Keeping your feet together, raise the knee up and then return it to the starting position. To target the right muscles, don’t move your pelvis and don’t let your neck bend down.

Repetitions: 15-20 reps for each side

Effect: You’ll work your oblique abdominal muscles.

Starting position: Bend one arm and use it for support. Stretch out your legs, lift your pelvis up, and place your other arm on your hips.

Bring your pelvis down and then return to the starting position. Try to keep your back straight and don’t swing your body to the front or the back.

Repetitions: 12-15 reps for each side

Effect: You’ll engage your abs and obliques.

Starting position: Bend one arm and use it for support. Stretch out your legs. Lift your other arm and the pelvis up.

Effect: You engage your abs and obliques.
