Strength training for older adults

Curious about strength training? Not sure if you can do it? You already are.

If you get out of bed in the morning, lift bags of groceries or suitcases, or have ever climbed a set of stairs, you have done strength training. Anytime you move your body weight you are doing what can be considered functional strength training.

By incorporating a more systematic approach, whereby you use not only your body weight, but external resistance (i.e. dumbbells, cables, tubing, etc.), you can target additional muscle groups or individual muscles.

When you strength train in a more formal way, you will improve your strength, endurance, and flexibility (more on that in another post) while at the same time reduce the risk of injury.

An added benefit to strength training is that it is targeted type of weight bearing activity that will allow you, when combined with walking or running, to slow down the development of osteoporosis and possibly reverse it. This is proof of being able to stop or turn back the aging clock.

If you are already strength training, keep it up. If you haven't started yet, start today!
