Body and mind
Each service plays a specific role in your balance. Together, they help you move better, recover faster and clear your mind.
-
Cardio boxing
For the bodyInterval cardio on Aqua Bags that works the whole body, legs to shoulders, with your core engaged on every strike. Endurance, power and coordination improve together, without stress on your joints.
For the mindReleases the stress of the day and demands total focus.
-
HIIT
For the bodyShort, intense efforts that push your heart rate into the high zone. More strength and power in 45 minutes, and a metabolism that stays active for hours after the session: the afterburn effect.
For the mindThe thrill of pushing your limits and an energy boost that lasts all day.
-
Pilates
For the bodyTargeted work on the deep muscles that support your spine. Posture aligns, your back feels lighter and every daily movement gains stability.
For the mindControlled breathing and real time to focus on yourself.
-
Stretch
For the bodyJoint mobility and active stretching to increase your range of motion. Muscles recover better, injury risk drops and you progress in every other class.
For the mindSlows you down, calms the mind and supports better sleep.
-
Sauna and cold plunge
For the bodyHot and cold contrast therapy: heat opens the blood vessels and relaxes the muscles, cold tightens them and calms inflammation. Faster recovery, less soreness.
For the mindAn instant feeling of clarity and well-being, a true reset.
-
Red light therapy
For the bodyRed and near-infrared wavelengths that reach beneath the skin and boost cellular energy. Used by athletes to recover faster, and as a skincare ritual for a radiant complexion.
For the mindA few minutes of calm and gentle warmth to reset.
These practices complement a healthy lifestyle and do not replace medical advice. If in doubt, ask your doctor.

I'm not athletic. Is this for me?

What should I bring?
Just yourself, your workout clothes and a water bottle. Boxing gloves are provided; hand wraps are required for hygiene, available to rent or buy at the studio. Training towels, showers, secure lockers, hair dryers and changing room essentials: everything is included.
How long is a session?
45-55 min of thoughtful, structured effort. Plan to arrive 15 min early to check in and gear up calmly.
