My name is Lev Tsimbler. I work out for years, in the last years I've also worked as a gym instructor. It amazed me that such high percentage of people who workout eventually get nothing in return (their progress towards the desired goal is either minimal or lacks completely). What makes this situation even worse is that there is very little serious and worth reading literature and it's hard to distinguish among worth and non worth reading literature. This is one of the main reasons why this site was constructed.
