If I only knew about PE at 29. Man you have so many good years ahead of you and can accomplish great gains. Truthfully I believe that being slightly older gives one an advantage. You have maturity. With maturity comes strength. With strength, determination. Many of the younger guys, sometimes don’t have enough maturity yet to handle this task. Some do, don’t get me wrong. But very many just expect instant gains and when it doesn’t happen, they just quit trying. Or, there’s those that are doing it for all for the wrong reasons. If you are determined to do what it takes, willing to learn and follow rules and mostly say this is to please myself, the advantage is in your court.
Best of luck to you, from a 40 year old newbie.
