Chris Sharma - Witness The Fitness, V15

Chris Sharma - Witness The Fitness, V15 drops you into the Ozark Mountains of Arkansas for a front-row look at Sharma’s first ascent of the legendary roof problem “Witness The Fitness.” Pulled from Dosage Volume 3, this short film captures the intensity and creativity required to unlock one of the steepest, most iconic boulder lines ever climbed. What makes it unmissable is the combination of raw difficulty and unmistakable style: a full-body fight through a wildly overhanging roof where every move looks improbable until it sticks. At just over five minutes, it’s a concentrated hit of motivation—pure bouldering power, precision, and commitment—showing why this V15 has become a benchmark that’s been repeated only a handful of times.
