The Workout Manager gives everyone the ability to share their workout information with either just their “Workout Friends” or with “Everybody”. By default the software is set so that “nobody” can see your information. You control what information you wish to share with others from almost everything to nothing. It‘s your choice.
I really haven’t talked to Cathe about what information she will want to share, but the capability has been built in to the software to do what you ask. Regardless, everyone can always compare their 1RM total for every exercise with the statistical “median” average of everyone who uses the software.
