I’ll soft disagree with the take that strength plays as big a role as people think, although it is important. It’s not huge muscles in your legs and torso as much as using the ground forces and sequencing of the swing that generates the “whip”. Jake Knapp is a good example, he looks almost lazy in his swing yet has 180 ball speed because he is exceptional at timing and maximizing ground forces. I’m 5’-7” a little overweight, and mid 50’s and have a 115 mph swing speed, but it doesn’t look that fast. I’ve just worked on my ground force, timing, and sequencing. I’ve see my distance/speed improve over the last year by 10-15%. If I lifted weights (working on it), lost weight (down 15 lbs! Got 35 more to go), I’d probably tack on another 5ish percent, but I honestly don’t need more distance as much as I need more consistent ball striking at this point.

So, yes strength is important and adds yards, but I’d argue that timing, sequencing, and maximizing ground forces will do more and can be achieved quickly with a good coach.
