MUSCLE BEACH

On the beach in Santa Monica, a young Jack LaLanne is third from the bottom. Harold Zinkin does a back bend, supporting Deforrest "Moe" Most, who supports LaLanne, with Gene Miller on top. LaLanne was the spiritual father of the health movement that blossomed into a national craze of weight rooms, exercise classes and fancy sports clubs.
