i need a couple of exercises that i can do at home all by myself. i know i can walk and run but what else? ive started to do lunges and theyre making my feet hurt but thats fine. and if you havent realized already, im trying to lose about 25 pounds as soon as possible without hurting myself or my health. please, dont say anything that im going to have to show the whole world because im really a shy girl and i dont want my family to know about this issue. although my mom is trying to lose weight too, its embarassing. alright, well thank you!
