I've found periodization very difficult on the trainerize app. The first & foremost challenge I face is the ability to track total volume per body part. I currently have to do this off-site in a spreadsheet for each client. I feel as if it would be a fairly easy integration as the muscle group is tagged when you input an exercise i.e. you program a bench press & it's tagged "chest." Now if every time I program a "chest" exercise it would add up the Total sets & give me the number for each bodypart that would be extremely helpful.
something like this:
Total weekly volume
chest - 10 sets
back - 12 sets etc.
