As athletes transition from the acceleration and burst phase into the sprint phase of running, different muscles groups are engaged, each of which requires specific training. The Insane Bolt 2 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 2 operates similarly to the Leapfrog 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 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.
The Insane Bolt 2 includes:
- one 20 foot Slastix
- two waist belts
Remarks: also available with one waist belt and one shoulder harness for the trail runner
The Stroops Insane Bolt 2 comes in 2 resistance levels:
- medium resistance
- heavy resistance
