In no way am I stating that the way I suggested is the only way. It is just a SUGGESTION based on experience for what has worked for me. Everyone is different and what works for some may not work for others. That is the beauty of this forum. To probe through different ideas to help maximize your training.
By the way, 5'11" and 300 lb with 15% BODYFAT is quite impressive! I certainly hope when I am 50 that I can be in that kind of shape.
