You want to stay in shape-but what's the best way to reach your optimum fitness level? Take a tour through these pages and sample them all: circuit, peripheral, endurance, and strength training, as well as routines for toning. Work with free weights, or do glute and lower back raises, lying hip flexors, and crunches with the exercise ball. Improve core stability with twists, and use a variety of machines from the treadmill and Stairmaster to the Nordic Track and cable machine. And, they're all safe-because with such explicit movements, you'll never make any mistake!
