Stef Williams

WeGlow is a fitness app founded by Stef Williams that combines Pilates and strength training workouts in one place. Stef describes it as her 'first baby' and uses it to deliver structured programs, including specialist series for pregnancy and postpartum recovery. It is the central hub of her fitness business beyond social media.

Stef Williams is both — her bio describes her as 'Your Pilates & Strength instructor,' and her WeGlow app reflects that dual approach. She blends Pilates-style movement with resistance and strength work, framing her philosophy around helping women move, glow, and thrive through every phase of life.

The WeGlow postpartum PJ series is a specialist recovery program Stef Williams created and released through her WeGlow app, designed to support women in the weeks after giving birth. Stef has shared that the series played a central role in her own physical recovery postpartum. It sits within WeGlow's broader library of phase-specific fitness content.

Yes, postpartum fitness has become one of the most prominent themes in Stef's content. She openly documented her own recovery journey after becoming a first-time mum, was transparent about not rushing back into intense training, and built a dedicated postpartum program on WeGlow to support other women through the same phase.

Yes, Stef shared prenatal fitness content throughout her pregnancy, tagging posts with hashtags like #prenatal and #pregnancy. Her content philosophy is built around supporting women at every life phase, so she covered movement suited to pregnancy before transitioning into her postpartum recovery content.

Yes, Stef Williams is a first-time mother. She has documented new motherhood openly, using tags like #firsttimemum and #newmumlife while sharing content that ranges from postpartum workouts to travelling with a baby.

Stef Williams has a paid partnership with Ninja Kitchen UK, with sponsored posts referencing the Ninja Auto Barista product specifically. She has framed the collaboration around small, everyday self-care moments rather than hard fitness sells, which fits the lifestyle tone of her broader content.
