Getting more muscles leads to more strength (because the strength of the muscle is determined by the cross-sectional area).
But you can definitely be natually strong without having a lot of muscle.
And you can definitely get much stronger without getting much muscle.
In other words, any person with big pecs and triceps will be strong in bench (even without training). But strong bencher will not necessarily have big pecs/triceps to show.
That's the whole premise behind the popularity of the Anatoly gym pranks.
