Continuously alternate overspeed passing and resistance running. A SMART Toner safety elastic is attached to two swivel belts, allowing athletes to pass one another. Once the elastic is stretched it places the trailing runner in an overspeed condition, accelerating the trailing runner past the lead runner. The lead runner is now powering forward in a resisted condition. Also great for partner resisted lateral and forward lunges and single leg squats! 4' SMART Toner with 2-swivel belts.
