At first glance, it looks like a blue-rubbery hand grenade, but it's far more explosive than that: this piece of high-tech wizardry called the 'kGoal' is a Fitbit for your vagina. The high-tech Kickstarter project is a little biofeedback reader that gets inserted into the health-nut's vagina, and connects to a computer to track and measure how effective her Kegel exercises are. Kegels are actually really important for women's health, but without circuitry up there to measure what's happening, until now it's been hard to tell if Kegel exercises are doing anything. Now, with the kGoal, quantification of pelvic-muscle squeezes are finally being tracked and documented. Now, if they can only turn this into a video-game controller...
