Women-owned Saltwater Sweat Co runs small-group classes out of a West Lewis Street studio in Mission Hills using Gravity Training System glideboards alongside indoor cycling, Pilates, TRX, and BOSU conditioning. The GTS format loads bodyweight at adjustable incline percentages through a pulley-and-cable carriage, a reformer-adjacent movement pattern that sits alongside the spring-based equipment at SHIFT Pilates rather than duplicating it. Class caps stay in the single digits so instructors can cue form in real time and modify load for pregnancy, joint histories, and returning injuries. Personal training packages on the same Gravity rigs scale resistance in controlled increments, making the studio a landing pad for clients finishing post-surgical hip or shoulder programs at Spine & Sport Physical Therapy - Hillcrest, 5th Ave.. The studio absorbed the previous Evolve Fusion Fitness membership when ownership changed and kept the cycling-plus-gravity hybrid that anchors the class menu today. Endurance-athlete blocks pair a 45-minute cycle set with glideboard posterior-chain circuits calibrated for cyclists and runners rebuilding aerobic base through hip, glute, and hamstring loading.
