Pre-pool activation drill set for swimmers with underdeveloped back and shoulder endurance. The goal is light activation, not max strength: 2–3 sets of 8–12 slow reps, body weight or very light load, controlled tempo. Build muscular endurance in the posterior shoulder girdle that supports overhead arm position.
Driver: back + shoulder endurance to sustain overhead arm position during drill work. Should make the brush-past-thigh cue easier to maintain in freestyle (currently the cue carries into the full swim but breaks down under fatigue). Should also reduce the "struggle to lift the arm up and over during freestyle" pattern noted in 2026-06-12.
Jack tires quickly on overhead arm drills (carry-over finding from 2026-06-12, 2026-06-19, 2026-06-26). The cause is muscular endurance, not strength deficit. Heavy weights would train the wrong quality and add recovery load. Light bodyweight + slow tempo + high rep count trains endurance without recovery cost before a pool session.
Face-down, arms and legs lifted slightly off the floor in a slow alternating swimming motion. Lights up the upper back, glutes, and hamstrings in the same pattern the body uses in the water. Often paired with Y-T-I as the second activation drill.
