Here are five common mistakes people make.
> Not warming up. Your muscles need to adjust to aerobic activity, so increase your intensity gradually.
> Not stretching enough. Stretch your muscles right after your aerobic workout, while they're still warm, to improve flexibility, help you avoid injury and reduce the changes of stiffness.
> Not drinking enough water. Keep a bottle handy during and after exercise, as becoming dehydrated affects your mental and physical performance.
> Jerking while lifting weights. This can lead to injury and stop you getting the results you want.
> Leaning heavily on the step machine. This is hard on your wrists and back, and bad for your posture.
