the hii life
Our method is motivated by results, rooted in science
Unique exercises, combined with everyday function, allow you to build your inner athlete and take care of the day to day. In other words, our goal is for you to strengthen your entire body for lifelong strength and success. This approach is the coveted blend of six principles that produce the hii:Athlete.
The 6 principles of athleticism
hii sessions
We work in 30-60 minute group training sessions. These sessions are split between hii intensity conditioning sessions, hii serenity restorative sessions and our slower paced regenerating recovery sessions. It’s important to balance your time between all three disciplines. We will guide you on this.
What to expect from our hii:intensity sessions
The Metabolic after burn created through our hii:intensity resistance training intervals and cardiovascular exercise rocket fuels your metabolism for 24-48 hours after the workout.
This is achieved in a 20-30 minute window during every hii:intensity session – this is your moment, give it your all, get your hii.
The intensity builds progressively until we hit our metabolic blast. Make this count, this is where athletes are made.
Intensity is the key ingredient that’ll take you from “fit” to hii:Athlete!


What to expect from our hii:serenity sessions
Our serenity sessions are much more than ‘exercise’. They connect everything – the movements of your body, the oscillation of your thoughts and the rhythm of your breath.
Every serenity session will guide you in a state of calm to help restore your physical body, soothe your emotional state and regulate your nervous system. Linking breath with movement will help in alleviating stress, reducing anxiety, enhancing sleep, flexibility, balance and strength.
What to expect from our hii:recovery sessions
Taking care of your body in-between and after a hii intensity session is just as important as the workout itself.
We burn, but never burn out.
Your muscles need time to repair if you want to get the full benefits of hii:intensity. Our recovery sessions will improve your strength, flexibility and performance through a combination of trigger point tools, effective passive and static stretches and mobility movement flows – all whilst decreasing the risk of injury.
This is where all your hard work is rewarded – release, restore and s-hii-gh.
