During the Summer I went to the gym every day. Now I go about 3 times a week. I dont do cardio at the gym, I just lift weights. Cardio is free, and I think people who do long endurance cardio are wasting their time at the gym. Weight lifting could also be free, if you went into the woods, and picked up a heavy log. You can bicep curl, shoulder press, sqaut, deadlift, and even bench press with a heavy log if you bring a blanket to lay or or something. There are so many other ways to exercise besides going to the gym. You can run hills, run stairs, or run laps. You can swim, play sports, cycle, box, take martial arts, and more.
