Stronger Kegels, Stronger Orgasms.

Fun fact: Your pelvic floor muscles contract when you orgasm, and the stronger they are, the bigger and better those orgasms can be. That’s where the Smartballs Duo Weighted Kegel Balls by Fun Factory comes in—it’s a simple but effective way to work those muscles by holding a weighted ball inside your vagina. It’s basically a workout that feels good and pays off in the bedroom.

How does it work? Just insert it, go about your day, and let your body do the rest. You can also amp things up by doing squeeze-and-release Kegel exercises while wearing it. The internal weight moves around as you go, making your muscles work harder—and bringing those stronger orgasms closer than ever. Aside from the orgasm boost, the Smartballs Duo can help prevent incontinence, improve blood flow, prep your body for childbirth, and even help with postpartum recovery. It also gives you better muscle control, so you can really squeeze your partner during sex.

What makes this one special? The medical-grade plastic panels let you feel the internal weight’s rumbling more intensely than if it were fully coated in silicone. Plus, the tapered tip makes insertion easy, and the little groove at the base helps guide it right in. When you're done, just tug the hygienic silicone loop for effortless removal. For best results, we recommend using them with a water-based lubricant, and cleaning your exerciser and weighted balls before and after with warm, soapy water or anti-bacterial toy cleaner.
