🏆 Why Men Choose CoreForce™ Over a Personal Trainer
Most core training programs ignore the one muscle that controls everything underneath — the PC muscle. Your abs get trained. Your glutes get trained. But the pelvic floor? Nobody mentions it. That's exactly why most men plateau.
The CoreForce™ Trainer fixes that. The triangular steel spring compresses from 7KG to 35KG with a single turn of the dial. The LED display confirms your resistance setting so you're never guessing. And the 360° rotating head means you can hit the muscle from any angle your body naturally positions itself.
One tool. Ten minutes a day. The muscle your training program forgot.
What Our Customers Say

★★★★★
Finally training everything on my list
"Six weeks in. My squat jumped from 315 to 335 and I genuinely think this is part of why. The core stability carryover is real — not just hype. The LED tracks every session so I can see exactly where I'm getting stronger. Didn't expect to care about this muscle. Now I can't imagine skipping it."
-
★★★★★
Best gear I've given my training partner
"Bought it for myself after my BJJ coach mentioned pelvic floor work. Threw out the idea, came back to it after a back injury. Two months later my core is the strongest it's been. The 35KG setting is actually hard — don't let the simple design fool you. I've already ordered a second one for my training partner."

★★★★★
Portable & Lightweight
"Thought it'd be a toy for phones. Used it to rebuild a cabinet. The thing is no joke — 35KG resistance, handle stays locked, LED doesn't lie. Compact enough for my gym bag. I use it every morning before my regular session now. Real results in about 3 weeks."

🏋️ Gym & Weightlifting — adds the missing link in your core training stack. Transfers directly to squats, deadlifts, and overhead press stability.
🥋 Combat Sports & Athletics — martial artists, wrestlers, and combat athletes have trained this muscle for decades. Now you have the right tool.
🪑 Desk Workers & Remote Teams — 10 minutes at your desk repairs what 8 hours of sitting breaks down. No gym required.
🏡 Home Training — no equipment, no space, no machine. Works anywhere. Morning, evening, travel. The muscle doesn't take days off.
FAQ
Will it handle serious resistance — or just light stuff?
Will it handle serious resistance — or just light stuff?
35KG max resistance. That's not light. Most men start at 7KG and can't hit 20KG within the first two weeks. The spring is a bold-gauge steel coil, not a toy. It will challenge you for months before you hit the ceiling.
Is it just for women, or a real men's training tool?
Is it just for women, or a real men's training tool?
Built for both. The PC muscle is anatomically present in both sexes — but in men it directly supports the deep core, lower back stability, and pelvic floor strength that most training programs never address. Elite athletes and military operators have trained it for decades. CoreForce™ is the first tool designed specifically with men in mind.
