Core Workouts

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 strength coach, nutritionist & yoga teacher from Oregon. After my career as a Division 1 sprinter & heptathlete, my passion for athletics transformed into something deeper: a love of movement in all its forms, & a calling to help others discover their own inner & outer strength. My training has evolved through many seasons, & so have my programs. Whether you’re brand new to strength training, an experienced athlete, looking to build muscle, improve your mobility, or simply feel better in your body, there’s something here for you. My philosophy is simple: train for life. I want to be strong enough to play for as long as I live & I want the same for you. Spend less time training just for the gym & more time building a body that lets you get out there & LIVE.

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.
