Sit Ups and crunch for the mean abs!

Two amazing abdominal exercises are usually incorporated into a Core workout. Full sit-ups involve the hip flexors and lower-leg muscles which are used to balance your exercise; always engage the abs as mush as possible to prevent lower back pain. The crunch is half of a sit up which focuses on only your abdominals.

Tip: If you want a flat stomach below the navel “crunch it”.
