SuperClient Marisa’s 6-Month Transformation

SuperClient Marisa’s 6-Month Transformation

Meet Marisa, a fashion journalist by craft and a regular CORE40 client.

This high-intensity workout gives me no excuse to say that I have no time to take care of myself. I’ve lost 45 pounds since July 2017, but I care more about sculpting my body than losing the weight. CORE40 has proven that I don’t have to work out for hours to get results! I love that in just 40 minutes, the workout effectively builds strength and tones my body.

I started working out again after two years of being a couch potato and doubling my body weight. At first, I joined ClassPass and tried various classes around the city, until I found CORE40. After my first class, I immediately signed up for the unlimited membership because I felt that CORE40 would be a great match for me.

Now, CORE40 has literally become my core. It is my morning routine to kick-start my day and I feel energized afterward.”

To Our Beloved Community,

Impact is one of our core values, and even in the face of uncertainty, we believe there’s always room to positively influence our community. We’ve been offering virtual classes since we temporarily closed our studios’ doors, and we are blown away by the incredible outpour of encouragement in your comments, emails, and messages. We’re committed to delivering at-home workouts and wellness tools during this temporary shutdown.

For those of you who would like to contribute to the ongoing creation of our digital wellness offerings, please feel free to do so, here. If not, that’s ok too. We’re honored to play a part in your journey, and we’re here to help you shine. 

While we can’t host you for class at the studios right now, we’re offering new video streaming classes on our social media pages to help you move at home!

With Love and Gratitude,

Team CORE40
