Function get_reps represent a wrapper function. This function is the
reverse version of the get_perc_1RM function. Use it when
you want to estimate number of repetitions to be used when using the
known %1RM and level of adjustment
Examples
get_reps(0.75)
#> [1] 10.01001
# # Use ballistic adjustment (this implies doing half the reps)
get_reps(0.75, mfactor = 2)
#> [1] 5.005005
# Use %MR adjustment method
get_reps(0.75, "%MR", adjustment = 0.8)
#> [1] 8.008008
# Use linear model with use defined klin values
get_reps(0.75, "%MR", model = "linear", adjustment = 0.8, klin = 36)
#> [1] 8
