"Anyone who's ever told you playing games on your phone was a waste of time has never tried this fitness gear. The Stealth Core Trainer forces you to hold a plank on a balance board-like piece of equipment. Add your phone and a free app to the mix, and it becomes an interactive fitness game that makes you sweat bullets, torches your entire core, and leaves your arms feeling like jelly."
"You tilt the board left, right, and forward as you play, firing up tiny stabilizing muscles and, hopefully, forgetting just how long you're holding that plank"
"The tilting and twisting provides a more dynamic workout than the regular old plank, and the random sequencing ensures that no two workouts are the same."
"This video game abs workout makes planking way more fun. The movement targets a total of 29 different muscles, including your abs, obliques, and lower back by twisting, turning, and rotating 360 degrees."
"Let’s be honest; ab day sucks. That’s what makes Stealth so genius: Instead of simply counting down the seconds until you’re finished, Stealth makes you focus on an integrated mobile game while doing an elevated plank."
"Make getting a six-pack more enjoyable with this gadget, which turns exercising into a fun game."
“Ever wish working out were a little more like playing games? Now, at least part of your workout can be! Stealth uses your core strength to control the action on your mobile phone screen, making static exercises like the plank more engaging — for your muscles and your brain.“
Stealth "is for anyone who may be looking for something fun, measurable and trackable"
