If walking is your exercise of choice, Dunn recommends mapping out a one-mile course. (You can drive the route in your car using the odometer or walk around a track at the local high school.) Then clock yourself while walking one mile. If you cover the distance in 15 minutes or less, you're walking briskly. "Believe me, we're not talking about strolling down the boulevard," says Dunn, sounding just a tad winded herself. "And we're not talking about stopping to smell the roses."
