Lesson Overview

2.51 – How Fat Gain Changes Muscle Efficiency: Gaining body fat can change how your muscles perform, not just how you look. A small increase in body fat can sometimes improve leverage and stability in certain lifts. This can make heavy weights feel easier in the short term. However, too much fat gain can reduce endurance and make movement less efficient. Extra body fat increases the effort needed to move your own body during training. Oxygen delivery can become less efficient, which affects conditioning and recovery between sets. Some lifters mistake this short-term strength boost for long-term progress. Over time, excessive fat gain often leads to slower workouts and quicker fatigue. Managing body composition helps keep strength useful, not just impressive on paper. This lesson teaches that fat gain has trade-offs that must be managed carefully. The goal is to support strength without sacrificing movement quality. When body fat stays in a healthy range, muscles work harder and smarter.
