thx for the help, I can touch my toes now, and I don't feel as much burn

i read somewhere that learning to do the splits would help a lot, and once u learn it, you can add a lot of variations to a lot of moves, so i'm gona try to learn it. if u know how to do the splits or know ne1 who does, plz tell me.
just one more question: is it harder to increase your flexibilit as you get older?
