Most students will progress at a faster rate with a higher number of swim lessons per week. This would ideally place intensity at two to three swim lessons a week.
One swim lesson a week is by no means detrimental to a student’s progress, merely resulting in a slower rate of improvement.
For optimal conditions, a routine should be established. Keeping the swim lesson time and day consistent will help them remember and effectively perform the swim skills they have learned from previous swim lessons.
