Virtually every movement the human body makes involves the use of the abdominal (ab) muscles. Without the abdominals holding the upper torso to the pelvis, the upper body would simply fall over backward. Because the abs are used to stabilize the upper body and core, there is a virtually limitless amount of core ab exercises that can be performed with, or without, weights. Some of the more common core ab exercises include crunches, sit-ups, squats, and deadlifts.

The most commonly performed core ab exercises are bodyweight crunches and sit-ups. A sit-up is performed by lying on your back, with your knees bent at a 45° angle. The hands are placed behind the head with fingers interlocked. The torso is raised off of the ground using the abdominal muscles, until the head is above the top of the knees and then the torso is lowered until the shoulder blades touch the ground. Typically, a number of repetitions are completed when doing sit-ups.

Crunches are performed almost exactly the same as sit-ups, except that the range of motion is limited to the middle part of the sit-up. The shoulder blades are raised off the ground and the head and shoulders are brought forward slightly and then back, without touching the shoulder blades to the floor. Both sit-ups and crunches are simple core ab exercises that will improve core strength, and can be performed almost anywhere with no equipment.


Other great core ab exercises include compound powerlifting exercises such as the squat and deadlift. Both the squat and deadlift rely heavily on the abdominals for support throughout the exercise range of motion. The front squat, which is a slight variation on the traditional squat, makes particular use of the abs due to the more upright position of the upper body. Any exercise that involves lifting a weight off of the floor will recruit the use of abdominals in at least a supporting function, which, in turn, strengthens the abdominal muscles. While the squat and deadlift generally involve heavy weights, the basic exercises can also be performed with smaller and lighter weights for beginners.

Remember that any time the upper body is used to move something, the abdominals are used to support the movement. As a result, although the aforementioned are traditional core ab exercises, anyone wishing to strengthen or tighten the abdominal muscles can easily improvise ab exercises with items commonly found around the house. Make sure to always perform exercises with the correct form, however, to prevent injury.

I feel like the greatest of the ab workouts is dancing. You might not think so, but you can do so many crunch-like moves while standing and moving around that can really carve out a six-pack!

I had been doing crunches for years before I tried a dance workout. In just a few months of doing it, I had better sculpted abs than I had gotten from years of crunches!

Also, this type of workout is more fun than boring crunches. You get to move to music while you tone yourself, and anything that is fun is easier to keep doing on a regular basis. It's hard to lose interest in dancing, but it's easy to lose the motivation to do a bunch of crunches.

I like using an exercise ball for core strengthening exercises. I can do a wider range of motion on it than I can while lying on the ground.

I can also work out both my back and front muscles. I feel like my upper abs and lower abs get an equal workout when I use the ball.

@Oceana – I started my abs exercise routine by doing sit-ups years ago, but I never really could see what advantage they had over crunches. With crunches, you only have to do half the work, and you still get all the benefits.

A friend of mine who is a trainer said that doing sit-ups can cause back and neck injuries. So, I decided to stick with crunches.

Of course, it's still possible to strain your neck muscles if you do it wrong. You have to always remember to use only your ab muscles to lift yourself. The temptation is to use your hands and neck, but that will hurt you rather than help you.

I'd like to get some opinions before starting a new abs workout. Which do you guys think is the better exercise, sit-ups or crunches? Why do you think this?
