Patent ID: 7998031

Claim:
A method of improving trunk or core musculature strength of an exercise participant in an aquatic environment, the method comprising the steps of: using a tubular apparatus in an aquatic environment, the tubular apparatus having a substantially constant buoyancy along an entire length of the tubular apparatus, the apparatus comprising: a generally straight and substantially rigid inner tubular member with an exterior wall, hollow interior cavity, and water-tight ends, the inner member having a length much greater than its diameter, a buoyant outer foam member substantially surrounding the hollow inner tubular member, the buoyant outer foam member having a substantially constant diameter along the entire length of the tubular apparatus, and the inner member being more rigid than the outer foam member but having sufficient flexibility to allow flexing when the apparatus moves through water during exercise; Stabilizing oneself with the tubular apparatus in the aquatic environment using the buoyancy of the tubular apparatus; and performing at least one vertical or floating exercise for improving trunk or core musculature strength with the tubular apparatus in the aquatic environment
