Tips for Building Muscle Fast
Rotate between muscle groups instead of grinding one station to 100% while the others sit empty, since Prestige requires every bar filled and a lopsided physique wastes stamina that could go toward a lagging group. Keep an eye on your stamina bar and duck into the Canteen before it bottoms out — running dry mid-set slows your rep rate far more than a short food break costs you. Early on, spend money on Max Energy and Energy Drink before Protein or the Money Booster, since more usable stamina per visit means more total reps per session, and Protein pays off best once you're already training in longer, uninterrupted stretches. Finally, don't rush to Prestige the moment it unlocks — banking a little extra progress first means your run to the next Prestige tier starts with a head start instead of from zero.
