Water sports have grown past water skiing, wakeboarding and surfing. Now, people are exploring even more new ways, like paddleboarding, to get exercising while in a lake or ocean. The Aqua Elliptica offers one such way to enjoy cardio while out on the water. This product is basically a water-friendly elliptical machine, similar to one you’d find in the gym. One Aqua Elliptica costs backers $2,500 with an estimated delivery date of September 2014. This new water device hopes to raise $50,000 in a 33-day Kickstarter campaign.
