Hey friends, it's Lizzie. Ten years ago, I walked into a kickboxing gym so nervous I almost turned around in the parking lot. I put my hand wraps on like mittens, gassed out in the warm-up, and was convinced everyone could tell I didn't belong. A decade, a nickname (“Liz Lightning”), and thousands of rounds later, I can tell you: that terrified girl in the parking lot made one of the best decisions of her life. Here's what those ten years actually taught me — and almost none of it is about throwing a punch.
1. You can do hard things — you just have to start
The hardest part of kickboxing was never the workout. It was walking in the door. Every excuse I had (“I'm not fit enough,” “I'll embarrass myself,” “everyone will be better than me”) evaporated the second I actually showed up. That lesson has followed me into every scary thing since: the business I started, the leap into real estate, putting my face on the internet. You don't have to feel ready. You just have to start, scared and all.
2. Confidence is built, not given
I used to think confident people were just born that way. Kickboxing taught me the truth: confidence is the residue of doing hard things over and over. Every round I finished, every combination I finally landed clean, every time I got tired and kept going — it deposited a little proof into an account I could draw from everywhere else. The confidence I have now didn't come from a mirror. It came from the bag.
3. Discomfort is where the growth lives
Nobody grows in the comfortable middle of a workout. You grow in the last thirty seconds of a round when your arms are jelly and your lungs are on fire and every part of you wants to stop — and you don't. I learned to lean toward that feeling instead of away from it. Now, when life gets uncomfortable, some part of me recognizes it: oh, this is the part where I get stronger.
4. Your body is capable of so much more than you think
Somewhere in my 20s I'd absorbed the message that my body's job was to be smaller. Kickboxing rewired that completely. I stopped asking my body to shrink and started asking it what it could do — and it answered with power I didn't know I had. Chasing strong instead of small is the single biggest gift training gave me, and it's the thing I most want to pass to other women in their 30s.
5. Community will carry you
I came for the workout and stayed for the people. A fight gym is a strange, wonderful family — sweaty, honest, endlessly supportive. On the days my motivation was gone, I showed up because they would be there. We're not built to do hard things alone, and finding “your people” will keep you going long after willpower quits. Ten years later, some of my closest friendships were forged on those mats.
6. Consistency beats intensity, every time
The people who transformed weren't the ones who went the hardest for two weeks and burned out. They were the ones who kept showing up — tired, unmotivated, imperfect — three times a week for years. I've watched consistency quietly beat talent and intensity in the gym and in life. Small, repeated, boring effort is the most underrated superpower there is.
7. It's never, ever too late
I started serious training when plenty of people think you're supposed to be “settling down.” What a lie that turned out to be. Your 30s aren't the beginning of the end — they're the beginning of the good part, when you finally know yourself well enough to go after what you actually want. I've seen women start in their 40s, 50s, and beyond and light up like a switch flipped. The right time to start is whenever you decide.
What I'd tell that girl in the parking lot
If I could go back and talk to the terrified version of me sitting in that car, I'd tell her: go in. It's going to crack your whole life open in the best way. You're going to find strength you didn't know you had, friends who feel like family, and a version of yourself who walks into rooms differently. Kickboxing gave me a body I trust, a mind that's harder to rattle, and the unshakable belief that I can figure hard things out. That's not about fighting. That's about living. And if you've been sitting in your own parking lot, scared to start something — this is your sign. Go in. 🥊💛
If you're thinking about it, I wrote a whole guide on kickboxing for beginners and why your 30s are the best time to start. I'll be cheering you on.
