Nah... you can do both. While this can work, lone wolfing like this can be pretty fucking lonely.

Applying this to myself, my biggest lifting gains came when I was running with some pro bodybuilders. We set/shared goals and then held each other accountable. I feel like this was written by someone that has never stepped foot inside of a gym at the very least. 

 That's not the same thing as just making an announcement. 

 It all started with the announcement.  

 I’d say it depends on the goal. Lifting and being healthy is a small goal that’s easy for others to support. Big goals should be kept secret and only revealed upon completion. 

 I think it also depends on who you tell.  Inner circle, yeah.  Every business acquaintance?  Nah
