What did @kastont actually say?
@kastont is selling a spring-loaded pelvic floor trainer and making a specific prescription: 100 fast squeezes plus 100 slow squeezes daily, targeting what he calls the "PC muscle," glutes, and sphincter simultaneously. He claims this builds both "endurance" and "real control." The device pitch is straightforward, anti-slip pads, adjustable resistance, heavy-duty spring. No wild curative claims, just a volume target and a product link.
That's worth noting upfront. He's not claiming this cures erectile dysfunction or fixes incontinence outright. The framing is fitness, not medicine. That restraint matters when we start checking the science.
Does the science back this up?
Mostly, yes, with real caveats about volume and technique. Male pelvic floor training has a legitimate evidence base. The question is whether 200 daily reps of a single movement pattern is the right protocol, and whether combining glutes and sphincter contraction is actually targeting the right structures.
A 2010 Cochrane review by Hay-Smith et al. confirmed pelvic floor muscle training produces measurable improvements in urinary continence and sexual function in men post-prostatectomy. A 2019 randomized trial by Dorey et al. in the British Journal of General Practice showed pelvic floor exercises improved erectile function in men with vasculogenic ED after three months of structured training. The mechanism is real: the bulbocavernosus and ischiocavernosus muscles, which the PC muscle group includes, directly compress the deep penile vein and support erection rigidity.
But here is where the video oversimplifies. "Heels together, squeeze in the deep muscles" conflates pelvic floor isolation with a broader hip adductor and glute pattern. Research on pelvic floor rehabilitation, particularly Bø et al. (2015, Neurourology and Urodynamics), shows that co-contracting superficial muscles like the glutes can actually reduce the specificity of pelvic floor activation in some patients. For training purposes in healthy men it is probably fine, but it is not the same as isolated pelvic floor work.
What did they get wrong (or right)?
Credit where it is due: the distinction between fast and slow contractions is clinically grounded. Fast-twitch fibers in the pelvic floor respond to quick squeezes; slow-twitch endurance fibers require sustained holds. @kastont calling fast squeezes for "endurance" is actually backwards by traditional definitions, endurance comes from slow sustained contractions, but the intent to train both fiber types is correct and supported by physiotherapy protocols.
What he got wrong, or at least left dangerously vague, is the volume. 200 repetitions daily with no rest days and no mention of progressive overload or recovery is not a protocol you find in peer-reviewed pelvic floor rehabilitation literature. Standard structured programs from Dorey (2006, Pelvic Floor Exercises for Erectile Dysfunction) use three to five sets of eight to twelve contractions with progressive intensity increases. Prescribing 100 reps twice daily to every man watching, regardless of baseline pelvic floor tone, ignores the real risk of pelvic floor overtraining, which can present as pelvic pain, increased urinary urgency, or paradoxical tension.
The device itself is a basic adductor resistance tool, not a true pelvic floor biofeedback device. Squeezing it between your legs trains hip adductors primarily. It can cue pelvic floor activation, but calling it a "men's Kegel trainer" is a stretch.
What should you actually know?
Male pelvic floor training is legitimate and underused. Most men have never heard of the bulbocavernosus muscle and most urologists do not routinely recommend pelvic floor PT unless there is a diagnosed condition. @kastont is pointing in a useful direction even if his protocol needs refinement.
If you have symptoms such as urinary leakage, post-void dribble, or erectile difficulties, a pelvic floor physiotherapist can assess whether your floor is underactive or overactive before assigning any exercise volume. Doing 200 high-rep squeezes daily into an already hypertonic pelvic floor can worsen symptoms significantly.
The device shown is not dangerous, but it is also not magic. A folded towel between your knees produces a comparable training cue at zero cost. Resistance and anti-slip pads do not change the underlying physiology. Train the muscle, not the product story.
