It takes physical exercise to build the body-and it takes a workout to strengthen the brain, too. Ivan Moscovich is a masterful coach, and he's created a selection of tricky conundrums to enhance every muscle of the mind. Because each puzzle must be completed in just one minute, there's a little hourglass timer (built into the book's front cover) that's custom-made to run for 60 seconds. Set it, and start the "circuit training" with the creative thinking puzzles: These graded problems develop flexibility, lasting mental stamina, and all-around mental fitness. Plus, they refine solvers' natural aptitude for the logic, number, visual reasoning, and word puzzles that follow. The culmination: a special Genius Gymnasium program that helps maintain the brain for years to come!
