Ben wants to start exercising regularly, but feels dumb asking how. He knows that in order to run or ride a bike he can't just start sprinting or pedaling like a maniac. He needs to prepare his body for these activities, but has heard mixed things about stretching before working out.
Here are the cold, hard facts on warming up, stretching, and cooling down.
The Basics of Warming Up It's important to warm up your body before any physical activity. Warming up for about 5-10 minutes goes a long way toward preparing the body for exercising, both physically and mentally. It also helps prevent injuries.
The term "warm-up" describes many light-aerobic and cardiovascular activities. When you warm up, you are literally warming up the temperature of both your body and your muscles.
Warming up also
- increases your heart and respiratory rate
- boosts the amount of nutrients and oxygen delivered to your muscles
- prepares the body for a demanding workout
Dynamic stretching uses many muscle groups in a sport specific manner and can be incorporated in your warm-up. In addition to warming up the body and preparing muscles that will be used in the activity, dynamic stretching allows for full range of motion of the joints.
Stretching used to be considered the main activity before a workout. Recent studies have called into question the benefits of stretching before working out. Traditional, or "static," stretching may lead to decreased muscle strength and performance. Consider doing dynamic stretches before and static stretching after a workout.
Stretching still can be a beneficial activity after you have sufficiently warmed up. The reason for this is that stretching cold muscles can directly contribute to pulled or injured muscles.
Stretching properly may reduce muscle injuries and improve athletic performance. In addition, stretching provides increased:
- joint range and motion
- blood flow to muscles
Stop if it hurts. Stretching should never hurt. If you have reached a point in your stretch where it hurts, relax to where it feels comfortable and hold the stretch.
Maintain each stretch for 10-30 seconds. Holding a stretch for any less won't sufficiently lengthen the muscle. Holding a stretch for longer may have negative effects on performance. Stretch the muscles gradually and don't force it. Avoid bobbing. Bobbing or bouncing while stretching may insure the muscle you are stretching. This damage may even cause scar tissue to form. Scar tissue tightens muscles and can get in the way of flexibility.
Remember to breathe. Breathing is a necessary part of any workout, including stretching.
Practice equality. Even if you are a righty, it doesn't mean that you should neglect the left side of your body. Make sure you stretch both sides equally, so all of your muscles are evenly ready for action.
If you play a sport, you should do-warm ups that go with that sport. The same is true for stretching. These types of stretches are known as sports-specific stretches, and they focus on the muscles that are used for your particular sport. For instance, if you play baseball you might focus on your shoulder for throwing or your forearm for batting.
Stretch regularly. To maintain flexibility, you should stretch at least 3 days a week.
Cooling Down After Your WorkoutThe most efficient way of slowing down a car or bike isn't by riding straight into a brick wall. The same way you have to gradually slow down either your bike or your car, you need to slow down your body after a workout or exercise: 5-10 minutes of slowed-down, easy activities will go a long way in helping your body recover from a workout.
Your cool-down routine can vary from workout to workout. It should include light aerobic activity and stretching. If you're running at a quick pace, you can slow down to a steady walk to cool down. Cooling down and stretching at the end of a workout help to:
- slow your heart rate to a normal speed
- return your breathing to its regular pace
- avoid stiffness and soreness of the muscles
- reduce any risk of dizziness and lightheadedness
- relax the muscles
