Ive made the argument for years that working out in the gym is by far the worst possible way to work it. Its just so boring and depressing and take sup your limited time.
Why would I spend an hour at the gym working out when I can play football with freinds, or go to a skate park or go mountain biking, or even just go for a run through a park? Its like trying to learn something by just doing math problems over and over again instead of working through actual problems.
