Q: Hey I have a few good questions for you Mike:

I'm 15 and since I live in the country I was wondering if these activities would be of any or alot of use:

The area I live in is quite hilly. I was wondering if I did a 1 kilometer lap a few times if that would amount to much/any weight loss if I did it every time I got home from school. Usually after I bike alot my mouse is dry and my legs feel like jelly, does this mean that I had a good workout or that I'm dehydrated and have bad leg muscles lol?

Are there any other activities that I can do outside in the coming winter months that can help me lose weight? I can't ski but hell I'll try it if it gives a good enough workout to be integrated into a routine.

So what kind of activities require little skill but can achieve a good amount of fitness (I can't skate, and I'll never be able to so that's out...I just can't keep balance lol).

Thanks!

A: Any of those activities -- running, biking, skiing will help you lose some weight. Running and skiing are more demanding than biking, so they'll give you more of a 'bang for the buck' in the same period of time. But any of them are certainly fine to do. Do drink water while you do them -- the dry mouth is a sign of dehydration and you don't want that.

If you're just looking to lose a little bit of weight and/or get a little fitter, then that's all you really need. If you're need to lose quite a bit of extra fat though, you'll want to have a little more serious program. At the very least, make changes to your diet that will help fat loss. Ideally you'd also take up some sort of weight training. To get a prescription for both of those things, fill out http://www.mikesfitness.com/content/fitnessguide specifying 'Lose Fat' as your goal. Good luck!
