The Insane Bolt targets the muscle groups needed to maximize both stride length and frequency—the two major elements of speed—during the sprint phase. The Insane Bolt operates similarly to the Leapfrog (pg. x), but with a longer 20-foot Slastix®, it now develops athletes’ form and sprinting strength. With the Slastix at a near maximum stretch (60 feet) between them, athletes begin sprinting simultaneously. The trail runner, propelled by the lead runner’s pull and Slastix® resistance, experiences the mechanics of running faster while opening his stride length; during this time, the lead runner trains within the acceleration phase. The drill ends once the Slastix loses tension. Includes two waist belts and one 20-foot Slastix; also available with one waist belt and one shoulder harness for the trail runner.
