My biggest habit (challenge) holding me back was FOOD. After 45 years of habits and a lot of them bad, it was very challenging to change what I have to eat on a daily basis.
Discipline/routine was a struggle...My way to overcome this was to treat the transformation as a full-time job and go at it like going to work every day. The easiest part of my journey was having a set program for weight training, following instructions from Troy and just completing what he asks me to do.
Don't listen to people saying "why bother you’re just old and that's how you're supposed to be".
