Frequently Asked Questions

Why are carbs higher during a bulk?

Extra carbohydrates help fuel intense training sessions and support the calorie surplus needed for muscle growth.

How is this different from calorie-calculator-weight-gain-bulking?

That tool sets the total calorie target; this breaks those calories into a protein/carb/fat split.
