Asked if he bulked up in the summer, Lukaku said: “A little bit of muscle, yeah. It was at the World Cup. I just felt great and I think I played great over there, and then when I came back it is a different type of style.”
While Lukaku scored four in six tournament appearances in Russia, plus twice in a friendly beforehand, he admitted the need to slim back down. “In the Premier League, I cannot play with the same amount of muscle as international football,” he said. “That was something that when I came back I knew straight away: ‘Nah, I cannot play in this style like this.’ I had to lose muscle basically. So you just stay out of the gym, drink a lot of water, and a lot of veg and fish and it helps.”

Dont recall him saying anything about being tired as the reason for bulking. And if you're tired putting on more mass isn't exactly the best idea.
For whatever reason he thinks going into international football you need some massive amount of muscle but in the epl he had to lose it. Then he goes on to say that to lose his muscle he stayed away from the gym and consumed fish and vegetables. What an odd concept. Why would u want to lose muscle. Lose weight fine. He could have went on a fat loss diet. He would still have lost a bit of muscle but would have lost mostly fat which is what he mostly put on anyway. It's just an odd thing To do for someone that should have the best coaches at his disposal.
