What Makes Coaching Different From Just Following a Plan

A mini-cut is a short, more aggressive period of fat loss, usually two to eight weeks, whose main purpose is to extend a building phase rather than to get stage-lean. This guide covers what a mini-cut is, why the building-phase logic matters more than the fat-loss framing, how to set the deficit and protect training while you run it, and the practical considerations (calorie headroom, dieting experience, motivation, and a productive end point) that determine whether it is the right choice for you at all.

Why Am I Not Building Muscle? Five Common Profiles Behind a Plateau

Plateaus are rarely caused by one variable in isolation. A typology of the five most common lifter archetypes when physique progress stalls: the Under-Fueller (training and nutrition quality high but energy intake low), the Overtrainer (excessive volume compromising recovery), the Chronic Dieter (too long in a deficit), the Junk-Volume Lifter (adequate volume but low training quality), and the Burnout Risk (everything covered except sleep). Each archetype has a specific limiter and a corresponding fix, and identifying which pattern applies matters more than adding new variables to optimise.
