If you're going to hone your body to a fine edge you need an exceptional grind. The Grind is a workout that helps you develop lower body strength and total body coordination. The difficulty level may not be very high but that doesn't mean that the intensity is not there. Pick your knees up to waist height each time you step, work your arms in coordinated unison and feel the difference it all makes to the way your body functions. Great for those just starting out but also a perfect tuner-upper for those who need a workout on days when they don't always feel like going flat-out.
