Are the tools only for women? #
No. The site is written for women 25 and up, so the explanations and default settings lean that way, but the math works for anyone. Every calculator that needs it has a Male/Female option, and picking Male switches the formula (calorie and macro math, body fat, heart rate zones, ideal weight, fiber, creatine and fitness age norms). The two exceptions are the Perimenopause Check and the BMI Calculator for Women, which are built specifically around female physiology.
Do I need an account or email address? #
Not for the calculators or the quizzes listed above. Results display instantly on the page and no sign-up is required.
The 60-second checks at coachluke.com/check/, the Weight Loss Quiz and the Supplement Match Quiz are different: they ask for your email before showing your result, and send you a free guide too. See How the 60-Second Checks Work.
Are the results medical advice? #
No. Every tool is an educational self-check built by a NASM-certified fitness and nutrition coach, not a diagnostic instrument. If a result raises a health concern, take it to your doctor.
