Founded in 2011 by Dave Thomas and Bryan Pritz in a converted boathouse, Performance360 has grown into a strength and conditioning franchise with its flagship gym at 4515 Gresham St in Pacific Beach, 92109. Thomas holds a Certified Strength and Conditioning Specialist credential from the National Strength and Conditioning Association, a B.S. in Business Administration from the University of Richmond, and has coached over 5,000 classes on the gym floor. Pritz, a former professional baseball player in the Boston Red Sox organization, co-manages operations and runs the brand's data strategy. The gym's programming blends physique development, barbell-anchored strength work, and high-intensity conditioning in structured six-week cycles, with group classes capped at 24 members. Athletes drawn to structured training often also work out at Six Blades Jiu-Jitsu Pacific Beach to add grappling and combat conditioning to their weekly split. Every class is led by a hands-on coach who never uses a microphone, and the brand runs a proprietary Coach Academy to develop and credential its staff across 17 or more locations nationwide. A post-session meal at Bare Back Grill near the boardwalk is a common refueling tradition among members who train at the Gresham Street location. The Pacific Beach flagship maintains a 4.9 Google rating across 166 reviews, with 61 percent of its membership base being women. The gym identifies as LGBTQ+ friendly and welcomes all levels, from first-time lifters to competitive athletes.
