If strength is reduced and weight reduced to match, then – setting aside the properly sciency technicalities of how such things interact at different proportions – there is no issue. Their altered strength matches their altered bodies and all is even.
Or to look at it another way, if they all collapsed under their own weight and died immediately, the modern races cannot be descended from them.
Of course, you literally cannot halve "everything" about a person, numbers-wise. Halving the height of something while keeping the same proportions brings it down to an eighth of its volume. So there's a degree of ambiguity in exactly what would be reduced and by how much.
I have wondered in the past, but haven't fully investigated, if the relative size of human and ancient might work out to them being 14 times the volume – that would add up if the ancients are a little under 2.5 x the height of a human, which from memory sounds about right.
