The practical route
Open the official Roblox experience, choose the training zone that matches your current goal, and test a few manageable exercises before chasing a personal record. Check reported codes before a long session, then use the planner to split your time between warm-up, main work, accessory or bodyweight work and a final review.
The aim of the first session is learning the loop, not maximizing an unknown formula. The game advertises Bench Press, Squat, Deadlift, cables, dumbbells, Pull-Ups and Dips, so those are safer starting references than an unsourced secret method.
