About this class

We offer Foundation classes on weekends as an introduction to the machine and workout for new clients. If you have a strong foundation, you can build anything on it. Our 40-minute Foundation class is a great place to start for those who are new to CORE40. If you are new to the studio, we strongly recommend that you take a Foundation class first so that you can get comfortable with our equipment, our 40-minute format and the fundamental exercises.  But don't let the name fool you into thinking this class is only for newbies. 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.

How to get there

It is very important to arrive on time. If you arrive late and are not present when the instructor begins the session, your space may be given to a standby client. There is no grace period in this situation. Once class has started and your space has been given away, it is too disruptive to ask the drop-in client to get off the machine. To avoid this situation, please arrive at least 10 minutes before class. Refer to our FAQ section for more detail on our late arrival policy and other helpful info.

Instructor and facility great! Music good. Instructor able to accommodate my back injury and give me modifications. Will definitely bring going back.
CORE40 Foundation with Katie
Not a good beginner class at all, the instructor didn't tell us a lot and everything seemed awkward.

CORE40 Foundation with Lisa
Instructor was super attentive and helpful to a newbie like me!
CORE40 Foundation with Lisa
Lisa was a really enthusiastic and supportive teacher. She made lots of effort to help me with the machine since it was my first time.
CORE40 Foundation with Brenda
The class was pretty intimidating for a newbie and for someone is more on the out of shape side. But the instructor was very accommodating and attentive to me!
CORE40 Foundation with Ines
I enjoy Ines's teaching style, she takes the time to provide some personal form correction and options for the exercises. After almost 2 mths of doing core 40 I think I am finally starting to get the hang of it and am definitely seeing results in terms of core strength.
CORE40 Foundation with Leticia
This class is great. Good transitions and challenging class. Prob one of the best core40 instructors I've had so far.
