At the Race Club we see a lot of swimmers that have an out sweep in freestyle. This swim technique mistake is more common than an in sweep but we do see a lot of both problems. We have found the FINIS Iso Paddle to be a great tool to correct the out sweep. The design of this product creates resistance in either an out sweep or in sweep pulling motion that allows the athlete to understand how to pull correctly. Check out how Gary Sr works with the Race Club Campers that all had a problem 'out sweeping' in their freestyle swim technique.
