Niki Rein
Niki Rein loves movement, personal growth, and barre fitness. She has pioneered barre fitness in Europe by opening Barrecore, the brand that introduced this dynamic style to the UK and grew into one of Europe’s most celebrated boutique fitness communities.
With a background in athletics, yoga, and the Tracy Anderson Method, Niki developed a results-driven approach that fuses ballet-inspired movement, Pilates, and strength training. Her signature style transforms bodies to be lean, strong, and resilient—while encouraging mindfulness and sustainable nutrition along the way.
Today, Niki channels her energy into mentoring expert barre trainers, consulting for wellness businesses, and coaching anyone eager to make changes in their lives. Her mission is to teach barre fitness with integrity, staying true to its roots, while helping people experience its full, holistic benefits. She’s all about sparking transformation, celebrating movement, and inspiring confidence from the inside out.
Born in Seattle, WA, Niki has built a career in the wellness industry fueled by her passion for all things well-being. She loves exploring new ways to move, nurture the body and mind, and inspire others to live fully and vibrantly.
