Fitness Calculators

Use these simple tools to explore a general estimate and plan a realistic activity week. They are educational aids, not personal medical advice or a substitute for professional guidance.

Adult BMI estimate

Body mass index (BMI) is a screening measure based on height and weight. It does not describe body composition or diagnose health.

Enter your height and weight to see the estimate.

For adults 20 and older only. Adult BMI categories are not appropriate for children and teens, pregnancy, or individual diagnosis. Discuss health questions with a qualified clinician.

Weekly activity planner

Divide a weekly movement goal into sessions that fit your schedule. The minutes are a planning aid, not a requirement for every person.

Choose your available days to see a simple breakdown.

Start at a comfortable level, build gradually, and include activities you enjoy. Rest or adapt the plan as needed.

How to use these estimates

Numbers alone do not determine what is right for you. Consider your circumstances, comfort and goals, and seek individualized advice when needed. Read our fitness disclaimer and beginner fitness guide.
