Suppose I want to say that he already had muscle and that is why it took him less time to make six packs.
Is this right if i say..
- He must have had muscle already otherwise it takes more than six weeks to make body like this.
I want to keep this sentence same. I mean , I don't want any other way to say same thing. I want to use " must " but I don't know how to say it properly.
