Work With Me

Hey there, I'm Jenn Hentel

Certified Personal Trainer, Nutrition Coach, & Author

After going through my own midlife health journey, I realized most fitness programs and diets weren’t built for women like us. They were unsustainable, too intense, too rigid, and too disconnected from real life and what moves us. 

That’s why I created ReDEFINE, to offer personal training, nutrition guidance and mindset coaching to meet you where you are today. Your plan. Your needs. Your desires. Your way. 

Let’s commit to living with passion, purpose and power. Living healthy, strong and pain-free doing what moves you because if something doesn’t move you, you won’t do it.

What You Get With ReDefine.

It’s personal coaching that supports your body, goals and your life. By moving your body and fueling it with nourishing foods and encouragement every step of the way, you will build strength, confidence and consistency that will transform how you look, think and feel.  


This isn’t a one-size-fits-all program.

1:1 Personal Training

Workouts that build real strength and shift how you feel about your body in the best way.


Mind-Body Support

Tools and perspective shifts to help you stay consistent, ditch the pressure, and trust yourself.




Nutrition Support

Simple, sustainable guidance to help you fuel your body without the stress.


Let's Do ThiS!

Prioritize Yourself.

I coach clients throughout Westchester County, NY primarily out of a private gym bordering Chappaqua. Whether we’re training remotely, at the studio, or in your space, we’ll create a routine that feels supportive, effective, and aligned with your goals.

I’ve lived in this area for over 20 years and love being part of the community. When I’m not working with clients, you’ll find me hiking through Rockefeller Preserve and soaking in the Hudson River views, a reminder to slow down and reconnect with what matters most.
