There is good news for people looking for tighter abs - some of the best ab equipment is inexpensive and small enough to easily fit into nearly any room in your house. This means you can get an effective ab workout without paying for a gym membership.

Stability Ball

A study conducted by the San Diego State University Biomechanics Lab and sponsored by the American Council on Exercise (ACE) found that abdominal crunches on a stability ball may be one of the most effective exercises for the abs, making a good stability ball an invaluable piece of equipment for anyone looking for stronger ab muscles.

When it comes to ab conditioning, there is no substitute for hard work. Some push-ups combined with a good diet and steady cardio can do wonders for your abs. If you can't afford to stock your home with exercise equipment, start small with a simple ab routine and go from there.
