Brentwood Gym Market -- Overview
Brentwood is a fast-growing East Contra Costa County city of about 65,000, transformed in the past 25 years from agricultural orchards (corn, peaches, cherries) into a master-planned suburban hub. Most residents commute via Highway 4 and BART (Antioch terminus) into the East Bay and San Francisco. Fitness sits in mid-tier chains and boutique studios at the Streets of Brentwood retail centre, plus a Trilogy active-adult community and several CrossFit boxes.
