Since I get this all the time, I'm going to try in this article to address a lot of these questions at once and give you a quick rundown on three of my personal favorite simple floor exercises for working out your abs.
1)Full Vertical Crunch. This one is great because it recruits all your ab muscles by getting your upper body and your lower body into the action.
Get on your back and bring your legs up so they're pointing toward the ceiling. Put your hands behind your head (or just hold your ears) and raise your shoulder blades off the floor - this will contract your abdominals. While you're doing this, stretch your legs upward as if you're trying to get your heels on the ceiling (point with your heels not your toes).
What you are trying to do is make your body into a U shape.
Lower yourself back to starting position.
Do between 10 to 15 reps on this one.
2)Long Arm Crunch. Now we're going to focus on your upper abs with this easy exercise. Lie on your back (on a mat if you have one) and stretch your arms out behind your head.
You'll know you're doing it right if your arms are near or touching your ears! Contract your abs to lift your shoulder blades off the floor. Perform 10-15 reps per set.
3)Vertical Leg Crunch, This one is especially good for your obliques. Lie face up on the floor, legs straight up and knees crossed.
In this exercise, imagine that you're trying to touch your chest to your feet... lift your shoulder blades off the floor and contract your abs to do this.
