The owners are curious about the differences in the use of resistance exercises among trainers

with different backgrounds, especially resistance exercises incorporated during the work week.

Write a query to display the trainer type, the maximum resistance included in a single training

session by each type of trainer, and the average resistance included in a single training session

by each type of trainer. Round the average resistance to $3$ decimal places. The resistance is

calculated as the pe$\_$weight multiplied by the pe$\_$reps. Limit the query to only include exercises

performed on Mondays, Tuesdays, Wednesdays, or Thursdays. Sort the output by the average

resistance.
