RacquetFlex

RacquetFlex is a tennis coaching and training brand focused on helping players build more powerful, consistent, and confident games. Its coaching approach draws on biomechanics research, more than two decades of playing experience, and reported student progress. The brand says its training system has helped players improve from the 3.5–4.0 to the 4.5–5.0 NTRP level, with particular attention to serves and reliable groundstrokes.

Players can choose from one-to-one in-person coaching in Long Beach, California, group clinics held in locations including travel destinations, and remote video coaching with personalized feedback, drills, and practice cues. RacquetFlex also offers online courses for independent training. The 5.0 Serve is an eight-week program, Weak to Winning Forehands is a step-by-step course focused on power and topspin, and Home Court Advantage is a home-based tennis course. A free five-day Serve Power Challenge introduces serve drills intended to help players develop more speed and smoother power.
