Do you get super tired when your grinding?

Whenever I'm grinding with a guy, even for only one song, my thighs get soo tired its a major struggle just to keep up. It gets really annoying and Im really sore when i get home. Does ayone else ever experience this? and how can i fix this?Do you get super tired when your grinding?

Stretch before you have sex.
take up bicycle riding. it really helps strengthen and tone the thighs and calves.
