Most Local Country Clubs and USS Teams offer HS pre-season training. If you would like to train with one of the local USS programs in the Winter, please visit their respective website to see if they are offering HS Pre-season training.
This training does not affect eligibility for the summer rec season as long as you do not compete in a USS meet after December 31st and you start training with your HS team on the first day of HS practice.
Be sure to check the LMYA website for County Meet restrictions.
