What players can rely on
Ultimate Gym Game officially describes three zones: Strength, Hypertrophy and Endurance. Choose Strength when the session is centered on heavier lift and PR intent, Hypertrophy when the goal is muscle-size progression, and Endurance when the priority is longer sustained work.
Those goal matches follow the ordinary meanings used by the game description. Exact bonuses, optimal repetition ranges and gain multipliers were not published in the available public sources, so this page does not invent them.
