Thinking about joining a gym? There are pros and cons to joining a gym, and it is up to you to decide why you should join a gym or why you should not join a gym. As many of you know, I have been in the health and fitness industry for many years and am a rep for Beachbody, which is a leader in at home workouts. You might assume I would tell you to workout at home. Personally, I love the gym atmosphere and still teach group fitness classes.
