Fitness calculators

Instant estimates for calories, macros, and weight-loss timelines — built for people who train, not spreadsheet obsessives. Use the numbers as a starting point, then talk to a coach about a real plan.

These tools run entirely in your browser. Nothing you enter is stored or sent to our servers.

Results are estimates for general fitness planning — not medical advice. For a body composition baseline and a program matched to your goals, book a free consultation at Level Up Gym.
