Why is Subaru so skinny?

He says he worked out every day.

Even if you're not doing it properly, gains are really easy at the start, so you usually get to a semi-fit state and hang there until you learn what to really do.

Why does subaru look DYEL? He said he had a 70kg grip strength. For an 18 year old, that is very impressive. Grip strength naturally improves over time and the average 30 year old grip strength is around 55kg.

Edit: 70kg grip strength is more than just impressive. Might be a world record.
