About FitKnicks

Hey, I’m Maddi – the face (and bum!) behind FitKnicks. I’ve spent years in the gym as a competitive bodybuilder, powerlifter, and boxer. I love lifting heavy, chasing goals, and feeling strong, but you know what I don’t love? Dealing with mild incontinence, visible panty lines, and awkward underwear issues during a workout.

Not that I would ever kink shame, but I imagine questions would arise if I did love those things...

After searching high and low for underwear that actually addressed these things (and coming up empty) I decided to make my own. That’s how FitKnicks was born: out of frustration, sweat, and a stubborn refusal to settle for anything less than confidence and comfort.

  • Seamless & higher waisted

    No more visible panty lines or awkward bunching. Just smooth, supportive undies that stay put.

  • Absorbent Where it Matters

    Our current leakproof pairs hold 20–25ml—enough to handle those little mishaps that can happen mid-workout.

  • Antimicrobial

    The seamless range is treated with silver ion tech for extra freshness and peace of mind.

  • Made for Real Bodies

    Whether you’re a powerlifter, a fit mum, or just love your athleisure, FitKnicks is designed to fit and support you—no wedgies, no rolling, no fuss.

STRESS INCONTINENCE

Going public on pelvic health

We talk openly about stress urinary incontinence and pelvic health, because it’s time to break the stigma and support each other.

At FitKnicks, we’re here to help women walk tall—whether you’re smashing a PB or just want to feel good in your leggings. We want you to feel supported, comfortable, and proud to be part of a community that keeps it real.

We’re about empowering women, starting honest conversations, and making undies that actually do what they promise. Because you deserve to feel confident—every squat, sprint, and step of the way.
