Wonderful way to tighten muscles and lose weight while swimming. Just get the Pool Treadmill. It is a smart device that sits at the end of your pool and makes it so you can swim in place by creating a moving current. You'll get all the exercise of laps without ever having to stop at the edge of the pool and turn around. Its powerful 24-volt DC motor produces 80 ft. lbs. of thrust and a maximum speed of 6 M.P.H., up to 11 1/2-minute per mile pace, resulting in a wide, deep current without turbulence that allows you to enjoy extended swimming exercise for up to 30 minutes in an in-ground residential pool. It requires no special tools, plumbing, or electrical work for installation because it is self-contained; simply roll it to the edge of your pool using its built-in handle and lower the generator unit into the water. Two rechargeable 12-volt DC Series 27 marine batteries (not included) fully-recharge in four hours and are housed in a battery compartment that rests on your pools deck, providing power for its patented propeller drive which generates the current. You can select your speed on the units dial for a light or vigorous workout.

Plugs into AC for recharging. 251/2 L X 24 W X 18 H. (105 lbs.) ($80). The Pool treadmill for $3,999.95 turns your swimming pool into a wonderful exercise machine. It's a tool that simultaneously increases stamina and improves swimming technique.
