At any level, movement and smooth technique take most tennis players the furthest.
But to progress to that next level and beat an opponent just above you on the ladder, being in better shape can be part of the ticket.
That ... and mostly a lot of practice.
And being in great shape can let you tolerate that greater amount of practice without breaking down from an overuse injury.

all true except that the op asked specifically how to achieve hitting a "heavy ball"... muscle strength or technique. And the answer to the question is technique.
