The Return of
Superwoman

β€œOne small step at a time, one little
improvement at a time, Jaci had me feeling
better, mentally and physically.”

Greg Korologos

I used to be Superwoman. I could easily throw my overstuffed suitcase into the overhead bins on airplanes and just as easily retrieve it. I could play basketball and touch football and I’d exercise in some form or other over long periods without tiring. But, guess what? Superwoman put on some years, like 60 or more. That wisdom found me visiting a neighborhood gym about three years ago, where I met a wonderful young certified personal trainer named Jaci Sellenrick. Her expertise, patience, compassion and encouragement kept me interested, kept me working out, and kept it all fun. My flexibility and endurance improved, the persistent ache in my joints disappeared, and those cumbersome doors open more freely. With her help β€œThe Return of Superwoman” can’t be far behind.

The best trainer I
have worked with

β€œFitness for a young person is an option, but
for an older person it is an imperative.”

Zemphria Raymond Baskin

Working with Jaci Sellenrick as my personal trainer for more than three years has been a very positive and beneficial experience. Jaci has taught me how exercise strengthens the heart and bones, improves circulation and reduces stress. She provides motivation to stay disciplined and focused, to set and surpass goals, to keep going and not give up. My routine workouts, which include cardiovascular exercises, strength training and flexibility exercises, have helped me deal with weight gain, diabetes, high cholesterol, and inactivity. Workouts are built around what the individual can do. Jaci Sellenrick does this extremely well. She is the best trainer I have worked with.

Keep the
β€œold lady” out

β€œI want to maintain my health and physical capabilities for as long as possible as I age. Jaci is helping me do it!”

I have been training with Jaci since 2019 and can tell you she is one of the best in the business! I want to maintain my health and physical capabilities for as long as possible as I age (in my 70s). We started meeting in person and when COVID hit, we switched to virtual sessions which has worked well for both of us. Jaci is very flexible and will work with you to meet your training goals. She uses up-to-date information and evidenced-based research and practice guidelines to provide quality training. She tailored the training to my needs and physical abilities. Jaci is an excellent communicator. She created a diverse workout program that maintains my interest. She doesn’t hesitate to change the exercise routines if needed, based on my physical capabilities, and won’t hesitate to challenge me either! Because of her, my goals are being met; lower blood pressure and weight and better strength and flexibility overall. I am working hard to keep the β€œold lady” out and Jaci is helping me do it!.

Rebuilding After a Setback

β€œI have become more accountable for staying in shape and more in touch with my body.”
Marsha H.
Read the full story

After a severe bout of cervical radiculopathy left me woefully out of shape, I decided it was time to hire a personal trainer. Jaci Sellenrick is knowledgeable in evidence-based exercise science, and she adapts my program to my needs. When I developed an inflammation of the piriformis muscle, which is quite literally a pain in the glutes, she was careful not to aggravate it and incorporated the exercises my physical therapist and chiropractor recommended. Working with Jaci, I've become more accountable for staying in shape and more in touch with changes in my body as I age. I recommend her to anyone rebuilding strength after an injury or health setback as well as developing a routine to stay in shape.

Training with Jaci has literally changed my life, from a 70-year-old couch potato to an amazingly strong woman (according to a recent independent professional fitness assessment).
