The STEALTH Core Trainer pairs with any smartphone and an Android or iOS app to run its fitness games, as well as track progress. The system comes with 2 free games, "Stealth Speed Gliding" and "Galaxy Adventure. This is what you'll be doing during STEALTH video game play, becoming a human controller (with abs on fire!) trying to shoot down targets, dodge attacks, and complete challenges. The padded STEALTH planking platform is mounted on its flat disc-like base with a "fluidity sphere" that allows the platform to tilt in all directions, as well as make circular motions. Of course, those 3 minutes are going to be spent in the dreaded plank position, whose difficulty will be enhanced by STEALTH's 360-degree mobility. Though it's called a Core Trainer, STEALTH makers say you can get a dynamic full body workout while using the device, and strengthen your core and back in under 3 minutes a day. STEALTH is a portable piece of fitness equipment designed to incorporate fun, or at least a level of distraction that will help you forget about the misery, into your workout. Hmmm . Change that to "Plank or play games!" and I'm in. I choose play games. The STEALTH Core Trainer invites you to "Plank and play games!"
