Liverpool midfielder Raheem Sterling admits he needs to get stronger.
Sterling says he is always working on ways to improve his fitness and is regularly found in the gym.
He told Forever Sports Magazine: "I'm always active, always working out, so you do get an athlete's body. I'm a bit skinny at the moment so I'm working on that, not too much [muscle], as I don't want to be too top heavy. I'll be in the gym working, trying to get internally stronger.
"I try to not lift too many weights. The people at the club [Liverpool] have been trying to get me to do core as much as possible - that's been a big factor for me so I try to do that at least a couple of times a week."
