Strength-to-Mass Ratio info

Weight-to-strength ratio or Strength-to-Mass ratio are terms used to describe ones physical functionality. We will call it Strength-to-Mass ratio and abbreviate it as SMR. SMR is critical for obstacle racing and functionality in life. Especially as we get older we have to fight to maintain our SMR.

Short definition of Strength-to-Mass ratio:

Strength-to-Mass Ratio (S-M R) is the force a person can exert divided by their mass. It is typically used in correlation with functionality; it is primarily of importance to people concerned with improving the ability to manipulate their own body (gymnastics, rock climbing, martial arts). These people should focus on exercises that increase strength-mass ratio, whereas bodybuilders, for instance, do not concern themselves so much with S-M R because the priority is more increase in bulk. S-M R is also beneficial for older people looking to enhance their lives through fitness. The crucial point is that your training must increase strength by a greater percentage than mass. Types of exercises that help: things such as weighted pullups/dips/pistols, cleans, snatch, deadlift, etc.

The next link is an online calculator for strength-mass ratio. I don't like that there is no pull up or lat pull down measurement as being able to pull your body weight up is extremely important in obstacle racing and in life.

The next link is to a paper on SMR levels. The higher your ratio the better your score.

Here is a chart to measure your strength-mass.

The next link is to a book on exercise physiology and some test to measure your SMR.

  1. Good stuff! Wish I could be as disciplined as you. I am trying though....

  2. The link above doesn't seem to be working
