The CrossFit Journal is a chronicle of the empirically driven, clinically tested, and community developed CrossFit program. Our mission is to provide a venue for contributing coaches, trainers, athletes, and researchers to ponder, study, debate, and define fitness and collectively advance the art and science of optimizing human performance.
PROGENEX doesn’t do the lifts, the pull-ups, the squats, the sit-ups, the presses, or the sprints. PROGENEX helps you recover from them. And, it provides the supplementation your hungry muscle fibers want, ensuring that your hungry muscle fibers are fed AND that your satellite muscle cells (those “baby” cells that lie outside your mature muscle fibers) are shaken awake—hard, so that they commit to becoming strong muscle fibers, too.
