Not everyone loves leg day. For one thing, it's just plain hard! Leg exercises also lack the ego-boosting, claim-staking, bare-chested flexing power that biceps exercises have. Take it from Arnold, though—skipping your legs will make you look like a fool. Just do a Google image search for "skipping leg day" and you'll see what he means.
"Chicken legs" are one of Arnolds's biggest pet peeves. "They are some of the biggest muscles in the body," he says. "When you work half of the body over and over but completely neglect the other half, you're leaving results on the table."
