The practical route
Choose Strength for 1-3 rep strength intent, Hypertrophy for 4-8 rep muscle-size intent, and Endurance for 9-16 rep cutting or sustained-work intent. These ranges come from the public UGG Trello and match the official zone names.
The Trello gives practical checked ranges, but the site still avoids machine-by-machine gain formulas. Use the planner as an editable session structure rather than a prediction engine.
