Gio's Fitness101 at 8227 La Mesa Boulevard, La Mesa, California.

I've been training at this gym for about a week now, and I love it here. My experience the first day: Gio greeted me right at the door, was super friendly and immediately made me feel at home. Also, the parking situation is great. There's plenty of free parking behind the gym- I've yet to have an issue finding a spot.
This gym is great for the more hardcore athletes, and it's a lot less polluted than other hardcore gyms in San Diego. The equipment is old school, there's a fantastic posing room upstairs for the bodybuilder types, and Gio has stocked the floor with everything you need for a successful workout. Everyone here is really nice and it feels like a family. I've trained during the typical business hours, and never once had to wait for a piece of equipment.
