Finding yourself inspired by Rhea and Keifer is inevitable, most of us Momentum devotees would agree, especially considering their extraordinary athletic feats. But the more time I’ve spent training in their circuit classes and one-to-one with Rhea, I’ve come to realize I’m most inspired by their uncommon ability to move others to do what seems well outside of their perceived ability. Incredibly, Rhea and Keifer manage to accomplish this not through force or uncomfortable intimidation, but with considerable shows of patience, attention, and gratifying good humor. This isn’t to say they only pitch soft encouragements—they are tough and expect toughness in return.
Rhea has coached and motivated me as a trail runner, helping me to train for my first serious mountain race, the Bridger Ridge Run, and my first long mountain race, the Old Gabe 50K. I easily could recount the obvious benefits Rhea’s time and attention has afforded me: reaching my physical goals, running harder and longer than I imagined within my ability, and feeling stronger than my own tired running routines permitted.
The less predictable benefits of Rhea’s partnership, however, have been more meaningful. She allowed me to more fully understand that I’m capable of moving close to the edge of my ability. She inspired me to feel confident enough to push toward distances and physical feats that appeared just beyond my grasp, which ranks her with a handful of exceptional people in my life.
