Some people have been discouraging me to go and hit the gym. According to one of my friends, once you work with weights your muscles begin to contract and causes to prevent your height to increase.
How true is this?
I'm starting to worry because, I really want to tone my arms, legs and have a flat stomach before the prom but I also don't want my height to stop growing.
Unless you're benching 400 lbs. I don't think you should worry about it stunning growth. My Lil brother is already taller than me he's 16 and can bench almost as much as me. Any it's pretty much a myth.
