(Help) How is math used in bodybuilding?

Physics. i.e. your bicep is curling weights your forearm length is so long weights held at that distance from the pivot point equals a certain amount of stress or negative (force to lift it up) i.e using exagerated lengths 10 lbs of weight with a 100' forearm would be harder to curl than ten pounds of weight on a 5" forearm.

diet is 95% math... the rest is actually doing what the spreadsheet spits out

Please start your paper with this sentence, 'Bodybuilders have to be able to at least count to ten.'

You're using instinctual mathematics every time you pick up a weight. Throughout your entire body minor adjustments and compensations are taking place as your nervous system calculates moments and alters forces around relevant fulcra.

As Shadow mentioned, half-life calculations are required for any consideration of nutrient uptake and decay or hormone release and clearance patterns.

I wouldn't really consider adding weights on the bar as being mathematics but you might get away with it depending on the level of your class.

Linear regression (and extrapolation) is involved in calculating a putative 1-rep max from a higher-rep max or vice versa.

Using Prilepin's table for consideration of optimal workload dependent on intensity requires some linear mathematics.

Calculating ratios of filler to active ingredients when making ones own capsules.

Using Brzycki's formula that estimates 1 rm from weights lifted at a higher number of reps

Find your own constant for each different exercise you do versus the 0.0278

The function Brzycki created can be found for each person by showing that muscle fatigue is linear versus exercise volume.

Using algebra, show how I got from Brzycki's original general formula to the user specific one.

yep....the one that works pretty well for me is:

1 rep = 1
2 reps = 1.07
3 reps = 1.12
4 reps = 1.15


then add 0.03 for each additional rep

lots of clever peeps in disguise in this thread
