Alright, guys, gather ’round. Today, I’m gonna share with you my little adventure into trying to hit the fastest tennis serve ever. Yeah, you heard that right. I got it into my head that maybe, just maybe, I could get somewhere near the pros. Now, I ain’t no pro, but I’ve always been pretty decent at tennis, or so I thought.
So, first things first, I started doing some digging. Found out the fastest serve ever recorded was by this Aussie, Sam Groth. The dude blasted a serve at 163.7 mph! I mean, come on, that’s like a small airplane taking off. And then there’s John Isner, another beast, who once hit a serve at 157 mph. Even Serena Williams, the queen herself, has clocked in at 128.3 mph. I was like, “Okay, these are some serious numbers. What have I gotten myself into?”
I decided I needed a plan. First step, get my hands on a radar gun. Yeah, those things cops use to catch speeders. Borrowed one from a buddy who’s into gadgets. Then, I started practicing. Now, let me tell you, hitting a tennis ball that fast is no joke. It’s not just about hitting it hard; it’s about the technique, the stance, the toss, the whole shebang.
- Day 1: Felt like I pulled every muscle in my body. The radar gun was laughing at me, I swear. Most of my serves were barely crossing the 100 mph mark.
- Day 2: Slightly better. I started to get the rhythm, you know? The twist, the snap of the wrist, and boom! Hit a few around 110 mph. Felt like a champ, even though I was miles away from the pros.
- Day 7: This is where it got interesting. I was getting more consistent, hitting around 115 mph. But I hit a wall. Couldn’t get past it. Felt like my arm was gonna fall off.
- Day 14: Frustration was setting in. I was pushing myself, but the numbers weren’t budging. Then, I remembered something a coach told me once – it’s not always about power, it’s about efficiency.
- Day 21: Started focusing on my technique more than brute force. I watched videos of the pros, slowed them down, studied their moves. It was like a light bulb went off.
- Day 30: I was ready for another go at it. Took a deep breath, tossed the ball, and swung with everything I had learned. Looked at the radar gun, and there it was – 120 mph. My personal best!
I know, I know, it’s nowhere near Groth’s or Isner’s, let alone Serena’s. But hey, for a regular guy like me, it felt like I had broken the sound barrier. Achieved a little something extra in my book.

My Takeaway
This whole experiment taught me a lot. It’s not just about how hard you can hit, but how smart you can be about it. Technique, practice, and a whole lot of patience. And you know what? I had a blast trying to up my game. It’s not every day you get to chase after something as crazy as the fastest tennis serve. Would I do it again? You bet. Maybe next time, I’ll crack 125 mph. Who knows?
