Looking for a new workout regimen?

Treadmill not cutting it for you anymore? Rowing machine too daunting? Have you considered running along the beach and swimming in the ocean, even in winter? Check out Gary Atlas (above), of Brighton Beach, New York:

Each day he runs six miles — always shirtless — up and down the length of the beach, from Brighton to Sea Gate, and then plunges into the ocean and swims out past the jetties.

In the summer, the swim may be a luxurious hourlong ramble. On the coldest days, with air temperatures dipping into the teens and water temperatures into the 30s, the swim shrinks to a zesty eight or nine minutes. These are the days Mr. Atlas loves.
