SPORT is an acronym that stands for Specificity, Progression, Overload, Reversibility, and Tedium. Specificity means focusing on the specific skills and muscles needed for paddleboarding, such as core strength and balance.

Reversibility warns against stopping training and losing gains. Tedium suggests adding variety and fun to workouts to stay motivated.
