The overlooked muscle group
Most women don't think about their pelvic floor until something goes wrong. Let's change that.
Pelvic floor muscles are invisible. There's no burn, no rep count, no mirror, no weight going up — so most women are left guessing, and guessing is why the habit dies in a week.
CLASP gives the squeeze something to push back against. The set becomes measurable, repeatable, and over in two minutes.
The problem isn't discipline
It's feedback. Every other muscle you train gives you something — a burn, a number, a heavier plate. This one gives you nothing at all.
Twenty minutes is a fantasy
Routines fail on length before they fail on difficulty. Two minutes sitting down survives a bad week. Twenty on a mat does not.
You shouldn't need an app
No pairing, no charging, no subscription, no notification asking how your pelvic floor is feeling today. Just a spring and a counter.
The two-minute set
01 02 03
How it works
Ten reps. Three seconds each. Once a day, sitting down, fully clothed.
Squeeze and hold
Draw the pelvic floor up and press inward. The steel spring pushes back — that's the part you've been missing. Hold three seconds.
Release fully
The release matters as much as the squeeze. Ten reps and you're done. The counter keeps track so you don't have to.
What you get
Six reasons it sticks
Resistance you can feel
A tempered steel spring replaces guesswork with feedback. You know the set happened.
Three muscle groups, one motion
Pelvic floor, inner thigh and glutes together — the most overlooked group in women's fitness.
It counts for you
An LED display tracks reps and sets, so the routine survives contact with a real week.
Two minutes, sitting down
At your desk, on the sofa, between meetings. It fits the day you actually have.
Adjustable resistance
Start on the lightest setting. Turn it up as the muscles catch up. Four levels.
Nothing to charge or pair
No app. No subscription. No Bluetooth handshake at 11pm. It's a spring and a counter.

Questions worth asking
Is this a medical device?
No — and we won't pretend otherwise. The Clasp Trainer is exercise equipment that adds resistance to pelvic floor and inner-thigh exercises. It isn't a treatment for any medical condition. If you have a diagnosed pelvic floor condition, are pregnant, or are recovering from surgery or childbirth, talk to your doctor or a pelvic floor physical therapist before you start.
How is this different from Kegel balls or an app?
Internal trainers and apps work the pelvic floor alone, and most people still can't tell whether they're doing it right. CLASP is external — you use it fully clothed, sitting down — and the same motion recruits the inner thigh and glutes. Nothing goes anywhere. Nothing needs charging.
How long before I notice anything?
Muscle adapts to consistent resistance training over weeks, not days. What actually predicts whether it works is whether you keep doing it, which is why we built the routine around two minutes instead of twenty. Results differ from person to person.
I'm postpartum. Can I use it?
Ask your provider first, and don't start before your postpartum clearance. A pelvic floor physical therapist is the right person to tell you when to begin and how much to do.
Should it hurt?
No. Start on the lightest resistance setting and build from there. If anything is painful, stop and speak with a clinician.
How do I clean it?
The pads pull off. Wipe them with soap and water or an alcohol wipe, then air dry.
What if it isn't for me?
Sixty nights. Use it properly, and if you don't want it, send it back for a full refund — pads and all.
Two minutes.
Starting today.
Sixty nights to decide. If it's not for you, send it back and we'll refund the lot — pads and all.
