Maximum Muscular Bodyweight and Measurements Calculator

by Casey Butt

The following calculator gives you an estimate of the maximum muscular bodyweight and muscular measurements (at roughly 8 to 10% bodyfat) that a drug-free trainee of your structure is likely to attain. It is based on equations I've developed through over 6 years of research and analysis of data from drug-free champions both past and present. In essence, this calculator scales the weights and measurements of the drug-free champions to your skeletal structure. The article presenting the equations utilized by this calculator can be found here: Your Maximum Muscular Bodyweight and Measurements

  • Height - your height without shoes.
  • Ankle - the circumference of your ankle at the smallest point between the calf muscle and the ankle.
  • Wrist - the circumference around your wrist just below the styloid process, on the hand side. (The styloid process is the bony lump on the outside of your wrist.) The hand should be open.
  • Bodyfat - the bodyfat percentage that you want to calculate your maximum bodyweight at.
