Product Description
What is the Green Zone?
The most efficient range of stroke counts for a swimmer of any height. These are derived from data on the Stroke Length of elite freestylers, and modified to give 'average' swimmers a realistic-but-challenging efficiency target. When you keep your count in this range, you make every stroke count. (We've made this chart available in both meters, and yards).
