Duraball Exercise Ball Review
A high quality exercise ball like the Duraball pictured above is the most effective tool you can use to get rock hard, chiseled abs.
Why do you think you NEVER see any of those crappy TV Gizmos like the Ab Lounge at the health club? It's because they don't work...
A club quality exercise ball meets the key criteria for getting the most effective ab workout:
We've established that the best ab machine is an exercise ball, but that only solves half of the question, because not all exercise balls are created equal.
The exercise balls you find at Sporting Goods stores and mass market retailers are poor quality at best. They're not made for prolonged use or larger users, and you can forget about using one for strength training with dumbbells unless you want to wreck it.
The exercise ball I recommend has a weight limit of 1000 pounds and a warranty of 3 years (compare that to a regular exercise ball with a weight limit of 200 pounds and a 30 day warranty) and is still going strong after 3 years in our gym after being abused by users from 5'-4" to 6'-4" tall and between 120 and 350 pounds.
To make things easy for you, I found the cheapest price for this club quality exercise ball from the most reliable source online - they'll ship one right to your front door in a few days with no hassles.
