I'm not sure what you're asking.
There's nothing in my exercise or eating routines that I would withhold, as I don't feel that's so personal that I would want to keep it secret. Isn't that the point of the profile? My colleagues ask me all of the time how I "do what I do?" My response is, "It's a priority in my life, my social life revolves around outdoor activity, and I get up very early to have the time for some of it." Most of the responses I get are "I can't do that." I always give the same answer and say, "You don't have to, do what fits your lifestyle or you won't continue." I just had this conversation with a colleague who is about 30 years younger than me.
Share what you want, I guess is my answer.
