How to Count Strokes Accurately
What Counts as a Stroke
Count each hand entry into the water. For breaststroke and butterfly, count each forward motion of both arms as one stroke.
Stay Consistent
Always count the same way. Use the same pool and distance for meaningful comparisons over time.
Track Progress
Record your SWOLF scores regularly. Small improvements (0.5-1.0 points) indicate better efficiency.
Time Accurately
Start timing on your first stroke and stop when you touch the wall after your final stroke.
