The Duo Balls provide a great-feeling object for the pelvic muscles to grip during kegels- you’ll have to flex to hold ’em in place, and what do you know, there is your workout! Satisfyer has provided some illustrated exercise positions for you to try, but you can also simply stand or walk around the room. Identical in shape, sexy silkiness and handy looped retrieval cord, the balls differ only in weight.
The lightest blue version, at 2.2 ounces is a perfect start point to Kegel practice. It will provide the least resistance and require the least amount of flex to keep it in place. If you find the blue balls a breeze, you can move on to the medium pink set at 2.8 ounces. The red balls are the heaviest, at 3.4 ounces, and will be a great incentive to work up to. Use a little water-based lube for easy insertion. Balls measure 6 inches in total length. Approximately 3 inches are insertable. Each ball is about 1.25 inches in diameter.
