My legs hurt so much! what did i do??

so in gym, we were doing warmups and we had to do lunges and then bunnyhops. we had to crouch down and hop forward, touch the ground, and continue on.
and now, it hurts to go to sit down, go up/ down stairs, basically bend at the knees kills my legs....

does anyone know what I did? or what I can do to stop the pain? asprine doesn't work, I tried that today.

that happens if you havent been exercising much, your muscles are starting to warm up, that happens to me sometimes, so I try to exercise more to keep it from happening. try taking a nice warm bath to soothe your muscles..

u need to start excersing more so that doesnt happen anymore

well your working muscles that you havent in a long time. When your getting bigger muscles they rip and repair themselfes, rip and repair, rip and repair...that's why. they ripped when you were working out and now they are reparing themselves a little bigger.

how long until the pain goes away?

that happened to me and streching meh legs out for a really long period of time and letting them rest helped. soo... try that! :D
