Holly Foss

Group Fitness Instructor

Holly Foss first discovered POP Pilates in 2015, and almost at once, fell in love with the fun, upbeat energy of the class’ signature format. As a beginner herself at that time, she felt instantly welcomed when she took her first class and noticed that everyone there; regardless of their age or skill level, seemed to be smiling, and having a great time together. Along with it being an awesome total-body workout, it was POP Pilates’ uplifting, positive energy, and all-inclusive vibe that made Holly continue taking POP classes regularly throughout 2016. She enjoyed it so much, in fact, that she ultimately took the leap to become a Certified POP Pilates Instructor in 2017. Holly is thrilled to be able to share her love of POP Pilates, and hopes to inspire and encourage those around her to continuously reach towards their fitness goals, no matter their starting point.

There is a gym on every corner in Southern California. There’s also at least one K-Mart or Walmart in every city in Southern California. But, would you be willing to go to a K-Mart / Walmart level facility for your health care? Probably not, so why would you trust your fitness, health and overall well being to a K-Mart level gym? K-Mart and Walmart are great for quick shopping and items that can be replaced often. The things at K-Mart or Walmart are inexpensive so we don’t expect the highest of quality. However when you need a wedding gift for your best friend or your boss you’re probably going to go to a higher end store. You can still save money at a higher store, but you definitely want a quality item. Right?
