Tech Insider’s Melia Robinson reports 420 Games founder Jim McAlpine is launching San Francisco’s Power Plant Fitness, the nation’s first gym where marijuana consumption is not merely permitted, but actively encouraged. Appropriately enough, McAlpine’s business partners include Heisman winner / celebrated weed enthusiast Ricky Williams (above, left).

“It won’t be a place to get high and just screw around,” Jim McAlpine, founder of the cannabis event series 420 Games and cofounder of Power Plant Fitness, wrote in a blog on the company’s website. “We are focused on the athletic side, not the cannabis side.”

In an email to Tech Insider, McAlpine explains that the gym looks to cannabis as a tool for focus and recovery. New members will take a “cannabis performance assessment” under the supervision of staff to determine the “most optimal ways to consume.” Some might find a bite out a pot brownie gives them the push they need to complete a circuit training workout, while others find it knocks them on the floor.

“We will be helping our members figure out how is best for them to ingest their cannabis,” McAlpine tells Tech Insider in an email.
