Group exercise is one of many ways the YMCA of Greater Westfield supports members in achieving their health and wellness goals. Our Group Exercise Programs improve health, encourage social interaction and with motivating music, are one of the most enjoyable ways to move and feel great. Highly trained staff members lead the programs and often tailor them to the specific needs of the community and individual.

Paula Simi - "So let's do this!"

My name is Paula Simi. I am a fitness instructor and have been with the YMCA of Greater Westfield since September 2019

I started my fitness role in Bend, OR and moved to Bozeman, MT and continued teaching. After moving to Westfield, I taught at Fitness First, then started with Westfield Health and Fitness. I also had a full time job with United Bank, then retired. I quit teaching for several years and became a member of the YMCA and found I missed being at the head of the class. I now teach classes and enjoy being up there.

You can find me teaching the following classes:

Monday/Wednesday Going Strong I 8:05 AM • Thursday Strength/Cardio 9:20 AM

My Going Strong I class is an intermediate level class working between basic and advanced levels of fitness.

My Strength/Cardio would be more on the advanced side, but every participant in class is able to work at her/his own fitness level.

Both classes takes you through 45 minutes of physical exercises, with floor routines using both low and high impact moves. I use energizing music to push you through movements and motivate you to rise through challenges. My goal is to engage with you and motivate, so you can achieve results and build your cardiovascular fitness level while improving your muscular strength. We use free weights, resistant bands and body bars. We also at times incorporate the step bench in our strength/cardio class.

My classes are energetic, fun and challenging and my goal is to take cardio and muscle endurance to the next level!

Teri Somers - "Fitness is like anything in life, you try and find your nitch. We have a great variety of dedicated instructors and diversity in our classes. Try them all and then come back again!!!"

I returned to the Greater Westfield YMCA as an adult member, after a long hiatus since learning to swim in the small pool and being a proud past member of the swim team under coach Jean C. Cole.

One of the wonderful fitness staff approached me for a substitute instructor position, and from there the passion for health, well being and teaching took over. My formal education includes Group Exercise and LiveStrong Instructor Certification. I also attended a Water Aerobics workshop. What I credit as priceless is the countless hours learning as a class participant under the direction of both Carol Palmer and Cindy Agan. I became a part of the talented and dedicated YMCA staff in September of 2014.

Currently you can find me as an Active Older Adult (A.O.A.)Fitness Instructor. 

You can find me teaching the following classes:

Going Strong 2 10:30am Monday/Wednesday/Friday. 

I will get you moving and grooving to some great music. Low/mild impact aerobics(20min), whole body stretches (10min), and strength/balance building exercises(15min) will assist you to achieve your fitness goals. We utilize the wall for pushups and squats. 50-55min, some equipment used if wanted.

Chair Yoga 12:15pm Tuesday/Thursday.

We use a yoga mat and chair, then guide participants into various yoga asana. We stretch and strengthen. Most folks are surprised how much can be accomplished in/with a chair.  Soft instrumental music helps with flow and relaxation.

Deep Poolates 4:15pm Monday, 10:45am Tuesday/Thursday.

We use pool noodles and hand weights to help you move in the water. If you are curious about exercises like balance beam squats, swing lateral scoops, or rocking horses...these innovative moves build and maintain balance, core strength and endurance. Stop by for a try!

Pool Fitness 9:05am Friday.  

Basics of low/mild impact exercises but done in the water which helps with resistance, but also helps the body with comfort.

I also teach Outreach Chair Yoga at the Westfield Senior Center where I have made lasting friendships and continue to learn from the perspectives of my seasoned clients.

My goal is safe and effective teaching with a blend of some fun and flair!
