About this class

If you have a strong foundation, you can build anything on it. Their 40-minute Foundation class is a great place to start for those who are new to CORE40. If you are new to the studio, they strongly recommend that you take a Foundation class first so that you can get comfortable with their equipment, their 40-minute format and the fundamental exercises. However, veterans are welcome and will be challenged, we promise! You will definitely break a sweat as you strengthen, tighten, tone and stretch your body in this fun, intense, music-inspired group class.

CORE40 Foundation with Carrie
1st time at CORE40. Didn’t know I would love a core workout this much. Kerri was great, gave me instructions and was very attentive
CORE40 Foundation with Marisa
Marisa is so helpful! This was my first core40 class and the first time I’ve worked out in a while so it definitely was challenging. Marisa really took the time to help and correct my positions. I will be taking the class again!
CORE40 Foundation with Catherine
Great core workout!
CORE40 Foundation with Jessica
Friendly and supportive staff. Fun and challenging workout.
CORE40 Foundation with Denise
Not good if you have back pain
CORE40 Foundation with Catherine
Amazing class! Cat is a wonderful teacher. She gave really great cues about where/how our bodies should be positioned, what we should feel, and accommodations. The pace is also great for people just getting back to or starting Pilates. Looking forward to my next class!
CORE40 Foundation with Catherine
Cat is great! She took the time to correct our form and spent more time on new people.
CORE40 Foundation with Denise
The class itself was good, however the instructor was not very helpful or engaging. As there were a few of us newbies, I watched as others (including myself) struggled on the machine with our posture and positioning. She never once helped to correct or provide guidance on our motions unlike other instructors I’ve been to. Looking forward to trying another class, however I most likely will not join with the same instructor.
CORE40 Foundation with Denise
I love Core40. This was my first workout with them and it was great!
CORE40 Foundation with Marisa
Overall, I think I just need to get used to the machine, but I wasnt sure if my form was right all class so needed a bit more instruction. I was really surprised when there was no stretching before or after class.
