TweetThat barely anybody @ their gym carries a log book? I don't see how people can memorize all their sets, reps, and mental notes for each exercise every time they do it! In fact I know they can;t most of the time they're GUESSING!! Im one of the 5 people at my gym that always carries a log book writing everythign down making sure I beat my log book every time, itsj ust strange that some people guess every time.
