Meet Betsan
FOUNDER, STIWDIO GLOW
Betsan de Renesse is the founder of Stiwdio Glow and has been teaching Pilates for over seven years. She holds an MSc in Strength and Conditioning and an undergraduate degree in Sports Science, with a specialist focus on women’s health and pelvic health.
Betsan founded Stiwdio Glow with the vision of creating a supportive space where women can move, build strength, and feel good in their bodies. Her work centres on helping women access exercise that feels safe, effective, and empowering at every stage of life.
She is particularly passionate about supporting women through key life stages and health challenges — from helping teenage girls understand their bodies and cycle health, to supporting clients managing conditions such as endometriosis and PCOS, as well as guiding women through pregnancy, postnatal recovery, perimenopause and menopause, hysterectomy recovery, and pelvic health conditions including prolapse.
Through Stiwdio Glow, Betsan’s mission is to ensure that as many women as possible have access to expert-led movement that supports their strength, health, and long-term wellbeing.
