What players can rely on
This Ultimate Gym exercise guide starts from the official Ultimate Gym Game description: Bench Press, Squat, Deadlift, cable machines, dumbbells, Pull-Ups and Dips, plus more than 31 exercises overall. The July 16 public Trello check adds specific cards for Hack Squat, Shoulder Press, Seated Leg Curl, Preacher Curls, Rear Delt Reverse Fly, Forearm Curls, Incline Bench Press, Lat Pulldown, Tricep Pushdown, Cable Row, Abs Crunch, Lateral Raise and Bicep Curls.
The Trello gives useful target-muscle notes for several exercises and marks other cards as stats coming soon. This page can now answer exercise-name and muscle-target queries better, but it still does not rank hidden gain multipliers or invent unlock requirements.
