Remember to do as what I said just now.He does not look like someone that fitness interests him very much.这两句话错在哪里?

Remember to do what I said just now.
He doesn't look like someone that fitness interests very much.

前一句去掉as
后一句把interests改为interest

第一句 as去掉 第二句 去掉him

第一句去掉AS， 第二句怎么翻译都很奇怪，去掉HIM

Remember to do what I said just now
He does not look like someone that fitness interests very much
