oddly enough, in my area i don't see many people using (i mean using seriously) the fitness equipment that is available for free, but from what I know, there are many more people choosing to join a gym. nothing wrong with that (i've never entered a typical gym or fitness center in my whole life and i don't plan to do it in the future, but that's just my own choice) as long as the same fact of requiring a gym membership doesn't turn into an excuse to stop working out. "i have to same my money for something else", "the lessons i'm interested don't match with my working schedule", "the trainer isn't as good as expected"... over the years i've heard it all.
on the contrary, if you choose to use the free equipment or you start a serious bodyweight program that does not require any equipment at all, you will put yourself in the position to be honest to yourself: you don't have excuses to skip your workout and, in case you skip, you have to admit your laziness. plus, places with free equipment are also great to spend some time with your friends or family. you can exercise together helping each other (which turns to be extremely motivating too), or just have some fun playing ping-pong or basketball. much better (and healthier) than waste some hour in the bar for the usual postwork drinks. as usual, the choice is yours.
