Our wellness instructors are here for you; whether you need help getting started, a refreshed program as boredom is setting in or you have decided to train for your first marathon, we can and will help. 

During your Coaching session you will be walked through all aspects of living a healthy life and leave with a clear program for success.  The goals are yours and the program is yours.  Typical orientations include the following components:

  • General introduction to the facility
  • Discussion around possible health concerns
  • Goal setting; short and long term
  • Warming up
  • Flexibility work
  • Cardiovascular training
  • Resistance training
  • Cooling down
  • Reducing stress
  • Program review

Our wellness instructors are always available to change, amend, or refresh your program whenever you need them to.  For more information or to make an appointment at the Seacoast YMCA in Portsmouth at 603-431-2334 and ask for Maggie Walsh-Lazzaro

Move your body. Challenge yourself. Change a life.

Challenge yourself to complete our Tri Inside the Y! Participants will have 30 days (April 1 – 30) to complete an iron-distance triathlon and earn a FREE T-Shirt!

NEW THIS YEAR — Join as a Team! Grab two friends and register as a team of three to work together to reach the iron-distance goals. Split up the miles, keep each other motivated, and cross the finish line together!

Feeling competitive? See where you stack up against other participants by sharing your weekly tracking sheets with a Wellness Staff Member. (Weekly tracking sheets will be available starting March 16 at the Welcome Center or ask a Wellness Staff Member.) Each week, we’ll update a progress board so you can see where you stand in the pack!

 

MAKE YOUR MILES MATTER

When we come together as a Y community, we create opportunity. Every $1,000 raised sends five kids to camp this summer. Your miles matter and so does your support. Consider raising funds or making a donation to help us open the doors of camp to more children who need it most.
