What to Do If You Are Underweight
For a skinny guy trying to figure out how to bulk up fast in a sustainable way, the path is clear. Eat more calories than the body burns, with special attention to protein, carbs, and healthy fats. Follow a structured strength training program built around big compound lifts or challenging bodyweight exercises, and steadily increase the difficulty over time. Limit excessive cardio, prioritize sleep and rest days, and adjust food intake based on weekly progress on the scale and in the mirror. With patience and consistency, even the skinniest frame can add noticeable muscle and size.
