GRF Stretch Reflex kit & Vector Map Bundle

Build a more powerful, efficient and controlled golf swing with two complementary GRF Golf training systems.

The GRF Stretch Reflex Training System uses resistance-based exercises to help you feel how force is created, loaded and transferred through your swing.

The GRFi Vector Map & Slider System helps you explore ground reaction force, movement direction, pressure and timing from the ground up.

Together, these systems provide a complete, feel-based training experience designed to improve speed, adaptability and control.

Includes all training equipment, travel bag and unlimited access to over 90 minutes of instructional videos with GRF Golf founder Marcus Bell.
