<human>: Give me a shortened version of the text

Wasn't sure where best to post so thought I'd try here first..

So I'm a 5ft 11in male, 23yrs of age. I weigh 20st (280 pounds if calculations are correct) I was a similar weight 2-3yrs ago but managed to drop down to 16st (so 224 pounds) I managed to do this by lowering portion size and eating and drinking less junk. 

Well over the last year I've had a pretty crappy year and put back on all my weight, I want to loose this, again, I know I can as I've done it before. I've started eating less and doing light exercise.

No to the reason of the post... I have very large thighs and this causes a problem when I go for longish walks or on warm days, no doubt you can imagine why... I was wondering how people here cope with it, is thee something (other than underwear) I can wear under my tracksuit bottoms when doing exercise? 

Sorry for the long post. Thought I'd add back story..
<bot>: suffer from chafing, need something to wear under tracksuit bottoms when exercise, eg walking or riding my bicycle.
