Everton striker Romelu Lukaku has revealed the secret to his monster frame.

The on-loan Chelsea forward says it was no luck of genetics.

"When younger, I was tall but very skinny," he told the Daily Mail. "When I was 14, I grew and started gaining muscles. So I started doing sit-ups, abs work, press-ups, strengthening my core.

"I'd do 100-150 reps each day. I knew if my core was strong enough, I would get fewer muscle injuries. So I used to wake up and start with sit-ups and abs straight away. I'd take a shower, go to school, train (for football) then go home and stretch.

"I used to run to school with my brother Jordan. It was two or three miles there and back. We'd do it every day. My parents didn't have the money to buy us bikes. It was nice, we enjoyed it."
