Optimize Calorie Burn by Adding This to Your HIIT Workout - Cross Fire (Inertia Wave)

Work your heart, lungs, and core with Cross Fire (Inertia Wave); add it to your HIIT routine for intense calorie burn. This is an advanced exercise and should be performed on a stable surface prior to performing on StrongBoard Balance. Exercises conducted with the INERTIA WAVE mimic a spring-like fluid movement and are designed to elevate the heart rate and work the entire body cognitively, providing overall engagement.

1. Start off by grabbing each end of the two inertia wave tubes, stretching them out enough to create resistance.

2. Step onto the StrongBoard platform with the sides of your feet against the platform handles. Because of the resistance pulling you forward, you can place your feet back about two inches from the normal stance. This will help counter the pull of the inertia wave.

3. Keep your body spring-like and stiff at the same time. Your ankle, knees, and hips will be flexed during this exercise but it is important to keep your abs braced. Hold the end caps of the tube securely and start to transversely flutter both tubes simultaneously on a horizontal plane. Move both tubes together as if emulating one continuous snake slithering through the grass. The Cross Fire movement is a spring-like oscillated side-to-side continuous pattern. This pattern results in a whipping motion.

4. Repeat for the desired amount of repetitions/sets.


Keep the spine erect and abs braced. For more of a challenge, you can squat during the Cross Fire. You can also go for longer bouts before rest.

StrongBoard Balance® utilizes MULTI SPRING TECHNOLOGY™ that works with your body to deliver the perfect amount of stimulation to keep your core musculature and stabilizing muscles engaged and contracted, while training your central nervous system, improving posture, proprioception and reaction time.
