A 12-Week Customized Strength & Flexibility Program
The Flex90 isn't a generic workout plan — it's a precision-built golf performance program designed specifically for you. Over 12 weeks, ASUN engineers a system that attacks the physical limiters holding your game back: weak core, restricted rotation, loss of power, and declining mobility.
Whether you're a weekend competitor or a daily player, Flex90 is built around your body, your schedule, and your lifestyle. Every session has a purpose. Every week builds on the last.
Each program is designed to fit your body, your game, and your lifestyle — because cookie-cutter programs produce cookie-cutter results.
