Several years ago I was in the process of losing some extra pounds. I was working out every evening and had gradually progressed to a relatively intense routine. And then I hit that dreaded point most people who are trying to lose weight hit at one time or another... a plateau.

I increased my exercise, I reduced my calorie intake a bit further, I did everything I could think of to shake myself out of that darn plateau. Then, at the suggestion of my boss at the time, I added a second workout session in the morning. That did the trick! Better yet, I found that I enjoyed the morning exercise and stuck with it for a long time.

I think we all have fitness frustrations from time to time. Whether you're trying to lose weight or training for a specific event or just trying to reach a personal fitness milestone -- as rewarding as fitness is, some amount of frustration is to be expected. But, like anything worth doing, if you stick with it, you'll get through the frustrating points and reap the rewards. Self Magazine asked readers for their fitness frustrations and then experts offered possible solutions.
