5'9"@148lbs.... and you want to lose weight? Nah, lil'fella, you want to build muscle and transform your bodys composition from a "skinny fat" twink into a respectible muscular physique.
stop eating junk food & drinking soda & beer. train 4 but no more 5 days a week and realize right now that nutrition and recovery are more important.
Now I will turn you over to the board members so they may destroy your self esteem.
