Insane Bolt 1 with belt
The Stroops Insane Bolt 1 with belt (singleman overspeed) for explosive acceleration exercises. The athlete is attached to an object with a 9m-long Slastix or held by partner. The Slastix is put under tension and as soon as the athlete starts, the extra resistance pulls him forward. This forces the athlete to run faster and take bigger steps.
The Insane Bolt 1 comes with a 9m Slastix Clip (in the desired resistance), 3m long cord, strap and anchor.
