Mt. Climbers On Stride Board

With booties on and one leg forward, while on a slide board, start a sprinting motion with alternating explosive leg strides. Leg speed is the goal as this should be done at the top of your athletic ability. Legs do not have to go to a full lockout position.

Keep your upper body still, and focus on driving forward with your quads and back with glutes.

Full body stabilization and cardio make this an excellent interval exercise.
