Need to build your cardio fitness? We've got the remedy! Feel yourself climb over fatigue as the effort duration increases on your way to the top of the mountain, before reducing on the way down so you can maintain intensity. When the timer hits, it hits like an avalanche!


Prepare for a strength building storm front! There's no turning back with this mix of isolation and functional resistance exercises. You'll be left ‘shaking at the knees', but the multiple timing and intensity of Thunderstruck will build strong lean muscle that will make it all worth it.


This is the new age of Radioactive TABATA! Push your individual max effort over repeated short bursts of intense activity. Treating each effort like it is the only effort will leave you gassed but feeling exhilarated. It's all systems go!

Thursday: TITANIUM

Fire away into this tough but results-driven superset workout. You’ll work the same muscle group on each paired station to increase muscle fatigue, but by the end you will feel bullet-proof!


This session will turn your body into a calorie and fat burning machine. There's a 'set goin' strong' with explosive power, speed and agility through plyometric and functional movement. Stay ahead of the game. Be Superfly!

Saturday: DOWN UNDER

Pretend you’re six-foot-four and full of muscles in this down-right gritty workout! The focus is on form and load with longer strength exercises mixed with uptempo, max effort cardio bursts. You better run, you better take cover!
