It helps to include:

• Which calculator you used (1RM, DOTS, Wilks, RPE or Strength Standards)
• The exact numbers you entered
• What result you expected, and why

Every reported calculation is checked against the published formulas and official coefficients. If we made an error, we fix it and reply to tell you.

What we can and cannot help with

We can help with anything about how this site's calculators work. We cannot give personal training programs, coaching, or medical advice — for those, speak to a qualified coach or health professional. Our terms and disclaimer explain more.
