About this studio

In just 40 minutes, you will experience the most revolutionary core-focused, full body workout in the fitness industry – one that not only works over 600 muscles per session, but in many cases works several hundred per exercise! In each group session, you will be trained by a CORE40 SuperTrainer, who is masterful at combining the benefits of Pilates and weight training (strength), yoga (flexibility & mindfulness), and cardio (interval training) with less time, more intensity, and no impact on your joints.

How to prepare

WHAT TO BRING/EXPECT... • A towel, if desired (CORE40 is an ecoconscious organization and does not offer towel service due to the water wastage it creates). • A water bottle, which you can fill using our filtered water system. • Please wear anything you might feel comfortable doing yoga or running in. • The CORE40 workout is done wearing grip socks (recommended) or barefoot. We have grip socks for sale at the studio. • Expect a high intensity workout!

How to get there

LATE ARRIVAL POLICY... Please arrive a few minutes prior to any class start time. Your spot will be held up to the minute class starts, then it may be given to a standby client. If it's your first class, you MUST arrive at least 5 minutes prior to the class start time, in order to get the machine rundown. If you do not arrive early, you will be asked to reschedule your first class, due to safety concerns. Refer to our FAQ section for more detail on our late arrival policy and other helpful info.

Not a foundations class
CORE40 Foundation with Ali
My first time doing Pilates on a machine, so a little tricky but overall a great introduction. I would recommend got first timers.

Hard to get used to machines
CORE40 Ramped with Nicol
CORE40 in general is a great workout. Class with Nicol could be improved with better mic volume as her mic is always too loud yet muffled as well clearer instructions
CORE40 Ramped with Dani
really well taught
CORE40 Ramped with Jessie
Jessies one of the toughest instructors at core40 by far, but in a good way. Motivating, encouraging, and provides personal attention even in full classes. 10/10!!

Jessie is AMAZING. I love her instruction, her energy, her vibe, and her moves! Absolutely coming back again :)
CORE40 Ramped [NEW CLASS TIME!] with Ashley
Teacher was rude and kept bragging about how much harder her personal workout was the day before.
