Annex Sports Performance

New Jersey

100 Passaic Ave, Chatham Township, NJ 07928, United States

Nearly twenty years. Countless athletes. One standard that never changed.ANNEX was built on a simple belief: serious athletes deserve serious coaching. From a basement gym to one of the region's most trusted performance facilities, we've developed amateur and professional athletes alike — not with gimmicks or one-size-fits-all programs, but with sound training principles, long-tenured coaches who know their athletes by name, and an obsessive attention to detail. Our facility has grown. Our methods have evolved. Our mission hasn't: put the performance and health of our athletes at the forefront of everything we do. The gym's proximity to Summit, Short Hills, and Millburn makes it a top destination for excellence in performance and fitness.
