Hi!
I'm Nikia Blumenthal
I’m so glad you’re here!
At Stretch, I bring together my passion for movement, recovery, and fitness to help you feel your best— whether you’re easing aches and pains, building strength, or chasing fitness goals.
As a biokineticist, I work with clients to manage pain, recover from injuries, and improve overall function.
I am an avid ice plunger, and love running Ice Bath Workshops.
I am also the proud coach of Stretch Run Club - where I help runners of all levels achieve their goals, build confidence, and enjoy the journey—celebrating every step and crossing finish lines together.
Whatever your needs, I’m here to guide you on your journey to better health, movement,
and well-being. Let’s get started!

Stretch Chill:
Ice Bath
I’ve experienced the incredible benefits of cold exposure, both personally, and with my chronic-pain patients, and I’m excited to share this transformative practice with you.
Whether you’re looking for a private plunge, a group workshop, a corporate team-building experience, or a custom private workshop, I offer tailored sessions to suit your need.
Ice bathing combines three powerful pillars: mind control, breathwork, and cold exposure.
The fusion of these elements creates the perfect environment to unlock benefits for both body and mind:
-
Accelerates muscle recovery
-
Reduces inflammation
-
Boosts circulation
-
Enhances mental resilience
-
Relieves stress and anxiety
-
Improves sleep
-
Strengthens the immune system
-
Increases energy and clarity
-
Relieves pain
I feel reborn, I feel like a WARRIOR!
