You need to get strong. Period.
I'm Coach Kristin, a Nashville women's personal trainer and strength coach who helps women get strong, have more energy, feel comfortable in their bodies again, and learn to get healthy without giving up their favorite foods.
We focus on:
• Lifting heavy-for-you and building muscle you can use
• Eating enough protein and fiber to fuel your life
• Never giving up the foods you love... including pizza 😉
• Simple habits that fit into your real life
• Getting your energy back so you don't feel tired all the time
• Reducing the aches and pains so you can keep doing the things you love
• Science-based coaching with no BS
I believe that when a woman is strong, it is more than a "look".
Strength is independence. Strength is long-term health. And strength is your daily reminder of what a capable badass you are, in and out of the gym.
This is an inclusive space; women of all backgrounds are welcome here.
When you sign up, you are also joining the Girl Gang - an incredible community of strong women who want to see you succeed! We celebrate each other's wins, support each other's struggles, and notice when you're not there.
I provide women's in-person personal training in Nashville, TN as well as worldwide via my online program called Stacked Strength.
If you're ready to build a body that lets you fully live your life and not be held back by fatigue, aches, or pains, including through menopause and beyond, you're exactly where you need to be.
You will never regret being strong, but the day might come when you wish you were.
Let’s build it now.

"Over the past year I can say I could have never believed how far I have come with her coaching."
"Kristin is knowledgeable on so many things that affect women. I came to Kristin as a 37 year old woman who needed a major change in my life. Over the past year I can say I could have never believed how far I have come with her coaching. I go to the gym regularly on my own, I’m consciously working on fueling my body for my workouts, I have an amazing group of supportive Girl Gang members who are so inspiring and great allies."

"I cannot recommend Kristin highly enough."
"Whew, what can we say about Kristin! She's a super dope female force for good, motivating women at whatever stage they're at to unlock their motivation, their drive, and whatever goals they have for themselves. She trains a super dope group of humans who are judgement free, encouraging, and super inspiring. If you're scared of going into a gym, scared of being judged, or just unsure of what you should be doing, I cannot recommend Kristin highly enough."
- Ellyn E.

"She met me at my experience level and has taught me so much!"
"I can’t say enough good things about what she’s done for me. I came into this a complete newbie to weightlifting - like zero experience, ever. She met me at my experience level and has taught me so much! Kristin enables me to be confident at the gym, and to TAKE UP SPACE! Her approach to nutrition is non judgmental and has worked really well for me. My initial goal was simply to lose weight, but with Kristin’s help, my goals are more focused on lifting heavier weights."
- Olivia H.
