Toking up while working out: Pair plan gym allowing pot use

NOVATO, Calif. (AP) - A former pro football star and an advocate for athlete marijuana use have teamed up to open a gym in San Francisco that they say will be one of the first in the world to allow members to smoke pot while working out.

Former running back Ricky Williams and Jim McAlpine, a snowboard company executive, said Power Plant Fitness will open before the end of the year. It also will offer edibles and topical gels for those who don't like smoking the plant.

Members will need a medical marijuana prescription to join, but that could change if California voters legalize recreational pot in November.

Carla Lowe, founder of Citizens Against Legalizing Marijuana, said it's not clear how pot affects the body but there's "zero evidence" it helps a person focus.
