I’m going to throw this in there now so we are all on the same level, squatting, leg pressing, deadlifting, rowing, pressing, dipping style exercises are great movements that will put the most amount of stress on your body. These movements are what your workout plan should be based around for an increase in strength, mass, and testosterone.
WE ALL are gifted with the ability to break boundaries mentally and physically, we can achieve whatever we believe, our thoughts become things, we manifest ideas and visions when focusing so strongly on them but obviously within the laws of physics and our genetic limitations, even then I am still not totally convinced, I honestly believe that anything is POSSIBLE, anything!
When I first started out, I just wanted to train to look good. The more I lifted the more I enjoyed the actual Physical aspect and challenge. Even today, although I have competitive goals, the training and the challenge of pushing myself are what attract me to bodybuilding the most!
