In San Jose, CrossFit has taken hold. The minimalist workout focuses on building strength, speed, and endurance, often with sandbags and tires—and it’s so in demand that at Crossfit Almaden, the coaches offer classes a whopping six times a day. That’s just one of the gyms in San Jose devoted to the regimen, which is as accessible as it is popular. As a veteran trainer explains in our CrossFit crash course, the workout can be scaled to any fitness level. And exercisers won't have to worry about learning how to use workout machines, as CrossFit equipment tends toward the bare bones rather than the complicated.
