Everything you need to know before your first HILI class, so you walk in ready.
Arrive 10 minutes early so we can check you in, show you around, and get you set up on the Xformer or in the Hot Mat room.
Slow, controlled movement, core-shaking holds, and intentional burn. Your coach cues every transition so you can focus on form, alignment, and breath.
You'll leave sweaty, energized, and stronger than you came in. Soreness is normal, especially in your core and glutes. Hydrate, stretch, come back.
Grip socks are required on the Xformer. If you forget anything, socks are for sale and towels and water are at the front desk.

HILI's first New York studio is coming to Flatiron. Presale is open: $1 down reserves a founding membership and locks in your monthly rate.

No. We recommend starting with Beginners Form Foundation, the class built to teach the movement patterns before you join a regular Full Body Sculpt. Every class has modifications for all levels.
Ten minutes early. That gives us time to check you in, give you a quick tour, and answer any questions before you're on the machine or in the room.
Between 90 and 104°F, heated with infrared. Warm enough to boost flexibility and calorie burn, not a sauna. Most people adjust within their first two or three classes.
Every class: water and grip socks. Forgot your socks? Grip socks are available to buy in-studio. HILI HOT: your own mat and a towel. No mat? Rent one in-studio.
