Nutrition Tool
Bulking Calculator
Estimate calories for a lean bulk, muscle gain phase or gradual weight gain. Build slowly enough that you can still recognise yourself in the mirror by the end of it.
General estimate for healthy adults. Speak with a qualified clinician or dietitian before making major dietary changes if you have unexplained weight loss, digestive issues, diabetes medication, an eating disorder history or another medical condition affecting weight.

How To Bulk Better
Extra calories are far more useful when paired with a repeatable resistance-training plan and gradual progression in the gym.
Hit a realistic protein target and use mostly proper meals rather than trying to bulk entirely through random snacks.
Scale weight jumps around. Review your average over two to three weeks before deciding whether calories need adjusting.
Faster gain is not automatically better gain. A controlled bulk is easier to manage later and usually feels better too.
