Aquatics at Seattle Athletic Club

Seattle Athletic Club offers a wide range of fun classes in aquatics. With swim conditioning being our most popular (think masters swimming), filled up with long time swimmers, newbies and triathletes alike.

Our water aerobics program continues to grow as our staff frequently attends new workshops and are offering the latest unique yet fun exercises to keep the class entertained and pushing their limits.

The majority of swim lessons are done on a private basis and are set up on days and times that fit with YOUR schedule. We offer these lessons to all populations.

At Seattle Athletic Club we offer some especially unique classes to cater to our members. They are set up on a seasonal basis and include swimming prep, open water swim training (skills, technique, and endurance training), and swim parties too!

Robert Hunt

Hi I’m Bob I’m 22 and moved to Seattle from the U.K where I studied Marine Zoology at Newcastle University. I have swum competitively since I was 7 and represented my Local Team, High School and University at national level swimming 50m and 100m freestyle as well as relays. As a swim instructor of seven years my employment and volunteer opportunities have given me valuable experiences working among children, adults and seniors of diverse backgrounds and abilities, some with severe limitations and disabilities. I also believe after teaching swimming for 7 years I continue to have the drive and passion, within swimming and life, to help people succeed in their own goals as well as trying to reach my own. In my spare time I enjoy soccer, skiing, surfing and scuba diving.

Class Policy

At SAC it is our mission to accommodate all our members the best we possibly can, although we cannot guarantee lane availability during class times. During posted class times we will do all we can to open up lap swimming lanes if it suits the format, the size, and will not disrupt the members that are currently in the class. Therefore when class in progress, please check with the instructor so that they can integrate you into a lane if appropriate.

*Lap swimming is open any time a class is not in progress* All swimming (outside of class times) is on a first come first serve basis. *Please note, you may be asked to move to an inside lane, as the outside lanes are designated for individuals with disabilities, parents swimming with children, or those utilizing the aqualogix equipment.

USA Swimming - Aqua Dynamics Swim Team

USA Swimming - Aqua Dynamics Swim Team (AQUA)

The Seattle Athletic Club is the premier host for the year-round, USA Swimming team the Aqua Dynamics Swim Team (AQUA). This team is dedicated to instilling a life-long passion for the sport of swimming by providing a positive, safe, respectful and fun environment in which swimmers learn how to swim competitively while learning the science behind the sport as well.

Through goal setting and training with a purpose, athletes will identify and overcome perceived limitations and achieve their true potential. We believe that the principles that guide AQUA will transfer to every aspect of our athletes’ lives.

Team members range from the ages of 8 to 18 and are divided into groups and practices based on ability and age. In order to join the team, swimmers MUST be able to swim freestyle and backstroke across the pool without hesitating, stopping or struggling.

There are three fundamental groups at AQUA; the Developmental Group, Age Group and Senior Group. Each group focuses on different aspects of competitive swimming with intensity, frequency and duration increasing as the swimmer moves up in groups. Groups are determined based on ability, commitment and age. We do not believe in a “one size fits all” criteria when placing swimmers, but instead look at each swimmer individually.

  • Developmental Training

    This group is designed for swimmers ages 8-10 who are new to competitive swimming. For safety reasons, swimmers MUST be able to swim freestyle and backstroke for an entire length of the pool without stopping or struggling.

  • Age Group Training

    This group is designed for swimmers ages 10-12 who have competitive swimming experience and who are able to commit to at least 3 practices per week. Swimmers in this training group must have previously swum for a club team, or have been approved by the Head Coach.

  • Senior Training

    This group is designed for swimmers ages 13-18 who have competitive swimming experience (summer league and high school swimming counts towards experience). Swimmers in this training group are committed to making at least 4 practices per week and all required swim meets.
