Lesson Overview

2.25 – Insulin Sensitivity & Muscle Partitioning: Insulin is not the enemy for lifters because it helps move nutrients into muscle cells. When insulin sensitivity is good, your body is more likely to send carbs to muscles for fuel and recovery. When insulin sensitivity is poor, more calories can get stored as fat instead of supporting training performance. That is why two people can eat the same surplus and get different results. Strength training improves insulin sensitivity because muscles become better at using glucose. Walking, sleep, and fiber-rich foods also help the body manage blood sugar smoothly. When your body handles carbs well, workouts feel stronger and muscle fullness returns faster after sessions. Poor insulin sensitivity can show up as energy crashes, stubborn fat gain, and slower recovery. This does not mean carbs are bad, it means timing, activity, and food quality matter. A smart plan uses carbs to support training and uses habits that keep the body responsive. This lesson teaches how to make your surplus work for muscle instead of fat. When partitioning improves, you gain cleaner muscle with less frustration.
