€990, icaros.com

Half gaming accessory, half coreburning balance ball, Icaros Cloud is an inflatable, connected training tool that hooks up to a smartphone, tablet or VR headset. It lets you dive (sometimes literally) into a world of online games, all cleverly designed to use digitally tracked movement to train balance and strength. Where else can you fly through snowy mountain tops while blitzing a full-body workout?
