you got to use your crosant!
Same as everybody else, lift. I'm 14 and i lift, just don't hurt yourself.
A 14-15 year old girl with big muscles should weigh between 135-160 pounds. A 14-15 year old boy with big muscles should weigh 145-195 pounds.
Scarily, yes, it is a good supplement for your body to gain non-fat muscles
no
No, you need to gain some weight.
Thats whats happening to me i weight 155 i gain pounds from out of no were
No, because my daughter is 10 years old and she is 51kg and 153cm. she tries to work out every day. 54kg for a 14 year old is perfectly fine but make sure not to gain too much
150 is not "fat" for a 14 year old, near this age muscles and your whole body grow, this puts a lot if weight on your body. I am 5'6 and im 151 and i only have a small body
lift weights
Yea
Fast food, junk food, and other fatty foods.
depends on what the 14 year-old did ;)
