Suits every fitness level!


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!


It's you against yourself in this cardio gauntlet! Set the standard in the first pressure set, then back it up in the second! Welcome to a new level of intensity - can you handle the pressure!


This sustained strength experience will take your body on a power trip! Push through short powerful sets and be ready to show us your maximum sustained power that will take your body to its limit.


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 battle with this unique strength workout! We pre-exhaust the target muscle group, then force it to adapt with whole body movements. Let your body do the talking to become a Warrior!

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!
