4th of July, .usa style. Wicker Park showed up and showed out to celebrate with us — sweat, community, and a whole lot of fun.
Huge shoutout to .usa for the cutest gift bags, and + for keeping us refreshed and fueled all day.
And can we talk about .palma1 and ?! These two competed in our plank challenge and held a plank on the reformer for 5 STRAIGHT MINUTES. We had to cut them off — they would’ve kept going. Absolute legends.
Thank you to every member who came out to sweat with us.

Iykyk. Heat warms up your muscles fast, so they stretch further and move easier. Less stiffness, more range. Your heart rate climbs quicker too, which means more calories burned in the same 45 minutes. Plus better blood flow = faster recovery.
Science-backed sweat, ONYX style. 🖤🔥
