The 2 Most Overlooked Muscles for a Massive SBD

Most lifters train the squat, bench, and deadlift by focusing on the muscles they can feel working the most. Quads in the squat, pecs in the bench, hamstrings in the deadlift. But big numbers are not limited by effort or intent. They are limited by weak links.

This guide breaks down the two most commonly overlooked muscles in each competition lift and explains exactly why they matter. You will learn how proximal hamstrings contribute to tension and power out of the hole in a narrow squat, how spinal erectors support efficient load distribution in a wide stance squat, why the upper back is the foundation of a strong bench press, and how glutes and core strength determine deadlift efficiency off the floor.

Instead of guessing which muscles need more work, this resource shows how different stances and positions change muscular demands and why strengthening the right areas leads to better leverage, safer movement, and bigger lifts. If your squat, bench, or deadlift has stalled, this guide helps you understand what is really holding you back.
