I Can't Lose the Last 10 Pounds

I'm a 24-year-old vegetarian and in pretty good shape, but I can't lose the last 10-15 pounds. I just can't do it. I've been doing my current regimen for about 2 years. Can you give me any advice on how to do this?

It sounds like you may have become accustomed to your current training regimen. If you stick with the same thing for a long period of time, your body becomes more efficient at dealing with the stress. So, experts advise that you "mix up" your training every 4-6 weeks. This is called periodization. This may help you burn some extra calories and also teach you some new exercises in the process.
