The classes

Our classes

Every format lives on the Obsidian® slide board: easy on your joints, relentless on everything else.

What we teach

Five classes, one board

Every class runs on the Obsidian® slide board, and every class offers options, so you set your own intensity. BURN and SCULPT anchor every week; the rest run in seasons.

Obsidian® BURN class working through a side plank series

On the weekly schedule

Obsidian® BURN

An hour of fat-burning, total-body conditioning you will not find anywhere else. Cardio, resistance training, core activation and reactive work flow together in one gliding circuit. Trainers offer options throughout, so beginners feel successful next to regulars. 400 to 800 calories.

An Obsidian® SCULPT class working through a barbell back squat

On the weekly schedule

Obsidian® SCULPT

Total-body strength training at its best. Barbells, dumbbells and cables meet the board to invite more muscles to the party, working every muscle group. More lean tissue means a faster metabolism, so you keep burning long after class ends. 350 to 800 calories.

Runs in seasons

Obsidian® I (Level 1)

A modified Obsidian® class built for anyone new to fitness or new to the board. Do not let the name deceive you: it is fun, challenging and a real workout while you learn the glide. Tell your trainer if you want pushing instead. 350 to 500 calories.

Runs in seasons

Obsidian® SOUL

The perfect fusion of yoga, the Obsidian® board and meditation. Good for the heart, the mind and the soul. Slower and more deliberate than BURN, with the same attention to form and the same trainers guiding it. Yes, you will still sweat.

An Obsidian® BOX class throwing a weighted hook combination

Runs in seasons

Obsidian® BOX

Mixed martial arts meets the board. Strikes and combinations from boxing, karate and muay thai load your muscles, then let you cut loose. No experience needed: give it three to five sessions to learn the basics. 350 to 800 calories.

Seasonal formats rotate through the year, so ask the studio what's next.

Every level

Made for every level

New to fitness

Start with Obsidian® I and a trainer who watches every rep. Options are offered in every single class, so you always have a version that fits.

Managing joints or injury

The board was born in physical therapy. Zero jumping, zero pounding. Tell your trainer what hurts and they will build around it.

Athletes

Ski, tennis, pickleball and golf all live in the lateral plane. So does the board. Train the exact side-to-side power your sport demands.

Longevity

Strength, balance and bone density matter more every year. Low impact training lets you push hard without paying for it the next morning.
