Unfortunately, I see that day in and day out. People get bit w/ the fitness bug, go balls to the wall, and get hurt, or stay so sore they just give up all together. Talking w/ a local exercise physiologist (that's what I do for a living), NOT a personal trainer at a gym. Most of those guys took an online course. Hell for $300 I could make all of you a certified "personal trainer." Most of those people don't know their ass from a hole in the wall, or their elbow. They know what some other trainer told them, or they read in the online test book, which covers about 5% of the knowledge base that goes into prescribing the CORRECT exercise program for someone. When you talk to someone, ask what college they got their B.S. from, if they didn't, walk away...hell run (just don't pull a hammy! ). Just my professional advice.
