Quiz: Fitness fact or fitness fiction?

Remember that saying, "No pain, no gain"? Not true. Exercise shouldn't hurt. A little muscle soreness when you do something new isn't unusual, but soreness doesn't equal pain. You don't need to make your muscles burn to know they're working. If it hurts, you're probably pushing yourself too hard.

Aerobic exercise is important. But a balanced fitness program also includes strength training and stretching, as well as exercises to improve balance and stability. Not enough time in the day for so many exercises? Never fear. Many activities include more than one exercise type. Take aerobic exercises such as walking and jogging. These activities increase your heart rate while helping you maintain balance and build strength in your lower body.
