That's Not a Bulk

Nutrition comic · April 14, 2026 · 6 slides

Bulking to build muscle should be done through a controlled, clean calorie surplus rather than eating excessive junk food. A clean bulk of 300 to 500 extra calories of nutritious food leads to lean muscle gain, whereas a dirty bulk results in excess body fat and a puffy appearance. Tracking progress with tools like GainFrame can help ensure weight gain is high-quality muscle.

The GainFrame mascot stands holding a large hamburger with a pizza box and a bag of chips at his feet, introducing the concept that eating junk food is not a proper bulk.

A dirty bulk. A real bulk.
A split-screen illustration shows the GainFrame mascot tracking a modest 500-calorie surplus on a chart on top, contrasted with him sitting bloated on the floor surrounded by empty chip bags from a 2000-calorie junk food surplus on the bottom.
A surplus: +300-500 cals. +500 cal. Not +2000 cals of junk.
