The punching bags at Milpitas Boxing and Fitness sometimes take the form a psychiatrist's couch. They absorb the emotions and reflect the triumphs of the professional fighters, children, and average gym-goers that treat them to regular pummelings. Milpitas welcomes guests of all backgrounds to wallop the equipment inside the sunny yellow walls of its gym, where instructors lead classes on boxing, kickboxing, Zumba, and general fitness. As they supervise spars inside their onsite ring or help kids to make waves with battling ropes, they encourage the simultaneous development of teamwork and personal growth. One-on-one sessions can also target more specific goals, such as learning how to throw in the towel with your non-dominant hand.
