Choose Strength Training for More Than
Linda Rellergert, Nutrition Specialist in St. Charles County, University of Missouri Extension
Regular, moderate strength-building activities can help you in many ways.
- Stronger muscles and greater ability to do everyday tasks like climbing stairs and carrying groceries and fun things like dancing and bowling.
- Stronger bones, reducing the risk of osteoporosis and fractures.
- Improved blood cholesterol and blood sugar.
- Better balance and less chance of injury during other activities.
- Improved posture, less back and arthritis pain.
- More self-confidence or sense of well-being that comes
from knowing you have the ability to do what you want to do.

you need to visit your doctor before starting a fitness
Dumbbells and ankle weights are available at discount stores as well as sporting goods stores. Begin with weights that you can lift yet give some challenge. Most women can start with a pair of two or three pound dumbbells; men with five or ten pounders. Adjustable weights are another option to consider.
Homemade weights can be used on a short-term basis. Fill
empty milk jugs with sand, bird seed or water, or fill socks
with beans and tie the ends securely. Carefully weigh any
homemade weights to make sure each one of the pair is the same.
Strength training guidelines
Always warm-up before exercising. For strength training, simply walk or march in place without weights or do gentle stretches for a few minutes.
Start with light weights, or even no weights the first week
to learn the movements. Concentrate on doing the movements
correctly in a slow, controlled fashion for maximum benefit.
Take three seconds to move the weight, pause for a second,
then three more seconds to return the weight to the starting
position. This is called a “repetition.” Counting out-loud,
“one, two, three up; one, two, three down” will help you keep
the correct tempo and prevent you from holding your breath.
In the following weeks gradually increase the weight you use for 8 to 12 repetitions of the same exercise. This is called a “set.” Rest a minute between sets. You want to do two or three sets of each exercise during each training session.
The goal is to challenge but not injure your muscles.
If you’re unable to do the exercise at least 8 times, the weight is too heavy and you need to use a lighter one.
But if you can easily do the exercise 12 or
more times, the weight is too light and you need to increase it.
You may need different weights for certain exercises.
Complete all exercises with ankle weights before moving on to
arm exercises. Include exercises that work opposing muscle
groups in the front and back of the legs as well as the arms.
For example, exercising only the biceps and not the triceps can
lead to muscle injury.
Cool down at the end of your workout by gently stretching the
muscles you’ve used. This will help reduce muscle soreness.
Do strengthening exercises two or three times per week, with
at least one day off in between sessions. On the off days do
endurance or flexibility exercises.
Don’t hold your breath during strength exercises as this can cause changes in blood pressure. This is especially true for people with cardiovascular disease. Breathe out as you lift or push, breathe in as you relax or lower the weight. This may not feel natural at first, and you will likely have to think about it for a while as you are doing it.
Avoid locking your arm and leg joints in a tight,
straightened position. People who have had hip or knee
replacement or other joint surgery should check with their
physician or physical therapist before starting a
strength-training program. There may be certain exercises or
movements to avoid.
Pain is a signal that you are using too heavy a weight or
that you have an injury. If you experience pain, stop
immediately and try a lighter weight. Although some soreness
when you begin lifting weights or when you increase weight is
common, it should not last longer than one or two days.
Do not walk around wearing ankle weights as they may cause
you to lose your balance and fall.
