Core Workouts

Get started today!

Welcome to the Core Library! This section includes a variety of core workouts you can mix and match with your existing training plan whenever you want to give your midsection a little extra attention. This isn’t a progressive core program, so there’s no specific order to follow. Think of it as a library of workouts you can come back to whenever you’d like. Some workouts require only your body weight, while others may use equipment or access to a gym. Any equipment needed will be listed in the workout description. A strong core is about so much more than building your abs. It supports your posture, balance, stability, and the way you move every single day. If you’re strength training with good form, you’re already engaging your core through many exercises, so you don’t need to do core-specific workouts every day. Instead, I recommend adding one or two of these workouts to your week, either at the end of a strength session or whenever you’re looking for a quick challenge.

About Claire Thomas

Online personal trainer

Howzit!? 🤙🏼 I’m Claire, a certified personal trainer, nutrition coach & yoga teacher from Oregon. After my career as a Division 1 sprinter & heptathlete ended, my passion for sport transformed into something deeper: a love of movement in all its forms, & a calling to help others discover their own strength from the inside out. In 2017, during my senior year of college, I launched CPT Fit Co. What began as a side passion project has since grown into a global community whose bodies & lives have been transformed by the programs you’ll find here in this app. Along my journey, I’ve explored a variety of different training styles while traveling the world & living a nomadic lifestyle (including three years of van life), which taught me how important it is to make fitness not only effective, but also flexible, fun, & accessible, whether you’re moving with just your bodyweight, unrolling a yoga mat on the beach, or strength training in a fully equipped gym. Here, you’ll find programs that reflect this journey, functional cross training, kettlebell flows, home & gym workouts, running programs, follow along yoga & mobility & so much more. My goal for this app is not about chasing aesthetics… it’s about falling in love with the process of taking care of yourself. It’s about honoring the privilege of movement & building a body that carries you through life with ease & joy. I’m so grateful you’re here. This is my passion & my purpose, & if these programs can help you move with more freedom, feel stronger, & live more fully…I’d consider that the greatest privilege of all. With gratitude, Claire

Frequently asked questions

How many days a week do you recommend doing core?

There’s no one-size-fits-all answer, but for most people, I recommend adding 1–2 dedicated core workouts to your week. Remember, your core is involved in almost every movement you do. If you’re following a well-rounded strength program and focusing on good form, you’re already training your core through exercises like squats, deadlifts, carries, presses, and planks. That’s why you don’t need to do core-specific workouts every day. Think of these workouts as a way to add a little extra challenge, build strength, and improve stability. Sprinkle them into your week whenever it feels right, either at the end of a strength workout or as a quick standalone session.
