Crunches

Abdominal crunches are one of the best moves you can do to build core strength. While this is a great exercise, doing it alone won’t get you a flat stomach.

Muscles targeted: abs

Start by lying on the ground, put your feet back by bending the knees and place your hands behind your head. Slowly, tighten your abdominal muscles and bring your head and shoulders about 1 to 2 inches above the ground. Maintain that position for a couple of seconds the lower your back to the floor. You’ve completed one rep.

Repeat for about 10 to 25 reps making sure that you maintain form for each rep.
