Swimmers of all abilities are invited to attend a clinic hosted by the Duxbury Masters Swim Team, a New England Masters (www.swimnem.org) workout group at Percy Walker Pool in Duxbury.  The clinic will be held on Sunday, Dec. 7 from 9 a.m. to 11 a.m.  The cost is $25 per swimmer, and will be limited to 24 swimmers.

Coach Jeff Rosen, who has 30+ years of coaching experience from US Swimming age group through NCAA Division I, will lead the clinic.  Fitness swimming using freestyle will be emphasized.  Questions will be answered, such as “what is surface tension?” and, “what is a good body position?” Butterfly will not be covered.  But starts, turns and backstroke may be covered, depending on time and numbers.

The Duxbury Masters Swim Team meets at Percy Walker Pool every Sunday at 5 p.m. with different levels of workout intensity available.  Masters Swimming (www.usms.org) is for people ages 18 and up.  Many members swim for fitness; some for triathlon training; some for competition and masters swim meets.

To register for the clinic, call Katherine Kardok at 781-659-7540 or e-mail swimschool@juno.com.  To become part of this small and friendly group, just come at 5 p.m. on Sunday.
