You won't find any treadmills or weight machines inside Primitive CrossFit. Instead, owner Matt Charney fills his gym with barbells, kettlebells, pull-up bars, plyometric boxes, gymnastics rings, giant tires, and ropes that dangle from the ceiling. Reading that list may be exhausting, but it's nothing compared to the workouts themselves, which are extremely welcoming to beginners. CrossFit is known for its intensity, and Primitive lives up to this reputation with a series of high-energy workouts that change every day to keep muscles guessing. With its focus on functionality, CrossFit can help individuals achieve goals that range from running a 5K to cartwheeling a marathon.
