Designed to generate maximum strength of the
upper-body muscles used during sprinting and running, the shoulder surge
builds resistance into shoulder conditioning and stretching exercises.
The Slastix® are attached from the the biceps straps to the back of the
shoulder harness, which is then anchored to a fixed object. This ingenious
“wear-while- you-play” design allows for the full extension and
rotation of the elbows and shoulders, which has the effect of improving
the athlete’s strength, form, and crucial elbow alignment, and hence
speed during sprints.
