Fake reconstruction.

Visit the Tower in London, look at the armor. Unless you're a pajeet you will find you're too big for most plate mails. They were skinny and trim.
Think like a fighter in low weight classes, track and field (Because that's more or less how they trained - jumping, throwing, sprinting), something like that. Battles were generally intensense short bursts followed by a breather, so their training emulated that.
