Position the ViPR in an off-set grip with the long end “away” from the intended moving leg. Lunge diagonally forward while shiftting the long side of the vipr “away” and return. Reverse crossover lunge the same leg while shifting the long end of the vipr “away” and return. Consider that 1 rep.
Maintain a long spine throughout and utilize the hips to “drive and catch” each direction of the movement.
