NxLabs Body Challenge is a physique-exhibition contest that emphasizes muscle tone over muscle size.

Physique guidelines for fitness competitions typically suggest a small amount of muscular mass; clear separations between muscle groups (but no visible striations); and leanness. The competitor should also represent a physically active body; provide examples of fitness, sports and adventure achievements.

Judges will be looking for symmetry, shape, and sculpting, as well as conditioning, leanness and how “athletic” (as opposed to brawny) their muscularity is.
