Hi guys,

well I am a 15 year old male, and recently I have noticed my legs have been getting tired easily.

- When I run
- Going up the stairs
- Walking uphill

^ That is what are making my legs tired, and I don't mean after like running 2 miles, or walking up a REALLY long steep hill, I mean not long after starting to walk it.

I am really really worried, I am only 15. You could say it's unfitness, but this is very recent it has come on. I maybe could exercise more, but I do exercise, am not overweight. Very concerned.

Please help me?
