Do you hate regular punishments, like so called "Time outs" or "Being grounded"?
If you do talk to your parents about a type of exercise instead.For example: Right now instead of being sent to my room for hitting my sister I have to do a certain number of push ups depending on how bad the thing I did was.
You can do this too! Just talk to your parents and work it out! IT'S THAT EASY FOLKS!!!
