One of the innovations of Crossfit was developing a series of\u00a0standardized\u00a0workouts<\/a> that allowed\u00a0athletes\u00a0to compare their level of fitness. \u00a0The workouts involve a combination of \u00a0many, many domains of\u00a0strength, agility, and endurance. \u00a0So it’s a great way to make a comparison of an individual’s ability.<\/p>\n

But I was thinking the other day that I wanted to come up with a way to measure ability at a more granular level. \u00a0So let’s say\u00a0athlete\u00a01 is a 150 lb. man, and athelete 2 is a 245 lb. man, and they do the same set of\u00a0exercise\u00a0at the same rate — who worked the hardest? I thought it must be the smaller man. \u00a0But by how much?<\/p>\n

Well I came up with a way to answer that question. \u00a0The Felsted! \u00a0The Felsted measurement is named after Angela Felsted<\/a>, a very talented\u00a0athlete\u00a0who was named \u00a0Crossfit Games MVP by the Crossfit Games MVP\u00a0Committee\u00a0[full disclosure: I am the sole member of the Committee].<\/p>\n

Anyway the idea is to measure pound-for-pound the output of two atheletes based on a 100 lb output standard. \u00a0For example, Crossfit Games<\/a>\u00a0workout 12.1 was max burpees in 7 minutes. \u00a0The Felsted standard\u00a0\u00a0is 100, based on Angela’s ouput (I’ve normalized weight and\u00a0results). \u00a0So how does that compare to a 200 lb. man did 125 burpees in 7 minutes? Simple! \u00a0Take a weight coefficient of .75, multiply by the number of burpees of 125, which yields 93.75, multiply that by 100 and you get .94! \u00a0So the 200 lb man exerted .94 of a Felsted! \u00a0Neat, isn’t it?<\/p>\n

The 12.3 WOD is a bit trickier because you have to account for the difference in WOD weights. \u00a0But if a 200 lb man had a score of 300, we adjust for the percentage of barbell weight,\u00a0yielding\u00a0an relative output of 363.45 (75 lbs vs 115 lbs for 32% of the workload). Then we adjust for body weight using a\u00a0coefficient of .75,\u00a0multiply\u00a0that by the relative output, divide by 243 (Angela’s output) and you get 1.12 Felsteds!<\/p>\n

I have no doubt the Felsted measurement of output will re-revolutionalize Crossfit.<\/p>\n

Well that’s it for now. \u00a0Thanks for stopping by and have a great day!
