The trouble with personal trainers is they always look so damn fit; exercising for an hour is bad enough without a bronzed Adonis staring at you the whole time. Enter BlazePod. A ‘flash reflex fitness’ device which is currently funding on Kickstarter, it’ll help you get fit without destroying your self-esteem. You pledge for a bundle of them, which communicate wirelessly with an app, which has loads of different exercises requiring you to leap and slam the BlazePods as they light up. Some of the activities are quite gamified and the app can measure your reflexes to a milisecond accuracy. A pack of two costs US$99, with delivery expected in October.
