WOAH good going man! That is one way of working out! Excellent!!!
Be patient with the weight loss, it will happen so keep on working as you are. The fact that you know you would not have been able to do those push-ups before you started means that you can definatly see a improvement in your physical ability - which is a huge bonus! Just imagine what it will be like after the whole 16?
