Surrounded by mountains on all four sides, El Cajon is known as “The Big Box”. To this Big Box, we just brought a very big can of whoop-ass, in the form of our latest and greatest Crunch gym. Packed with loads of cardiovascular and strength training equipment, tanning booths, a group fitness studio, a dedicated stretching area, and a team of mindbogglingly talented personal trainers, it offers residents everything necessary to get the ultimate workout experience.
