How it works.
The estimate uses the Epley formula. A set of 225 lb for 5 works out to an estimated max of 262.5 lb. It is the same formula Load It uses for the sets your clients log.max = weight × (1 + reps ÷ 30)
If you did a single, that weight is your max, and it is used as it is.
Sets over 10 reps don't get an estimate. The formula assumes weight and reps trade off the same way at 3 reps as at 30, and they don't. Past ten it starts to flatter you, and you would end up with a max you could never really lift.
The estimate is shown to the nearest half pound (or quarter kilo). The percentage chart is rounded to the nearest weight you can make on a standard gym's bar and plates, so you can put it straight on the bar. For a chart from a max you already know, use the percentage chart.
Load It does this for your clients every set.
Load It works out an estimated max from each client's best set, tells them the moment they beat it, and uses it to fill in any set you write as a percentage.
