For resistance exercise: You don't need to pump iron in a gym to do resistance exercise. Of course, if you want to go to the gym, I wouldn't discourage you. But if you prefer to do it at home, you can. I recommend exercise tubing if you're looking for a simple but effective way to do resistance exercise at home. Exercise tubing is inexpensive and versatile (you can do lots of very different exercises with them) and they are a great way to get started with resistance exercise. You can start with a set of four for about $20. They come in colors to denote the tension. If you order them, make sure to order the strap that allows you to attach the tube to a door, and if you want to work your legs, ask for leg straps. Here are some vendors that sell them:
According to the American College of Sports Medicine, by the year 2030, the number of individuals in the United States 65 years and over will reach 70 million, and people 85 years and older will be the fastest growing segment of the population. Some of you may already be there, while others may be approaching. But whatever your age, exercise can be beneficial. Below is a description of what happens to our bodies as we age and how exercise can make all the difference.
Crunch: It presents the same problem as the leg press. You flatten your lower back against the floor as you raise your head and shoulders and feel the squeeze in your abdominal muscles, then go back into an arch when you lower yourself. Although you aren’t using much weight when you do it—just a fraction of your body’s weight—you typically do lots of repetitions.
In a large study of 439 adults (aged 60 and older) with osteoarthritis who did either aerobic exercise (walking) or resistance exercise (weight lifting) for 18 months, participants in the aerobic exercise group had a 10% decrease on a physical disability questionnaire, a 12% lower score on a knee pain questionnaire, and outperformed non-exercising individuals in the study on the following tests: a six-minute walk test (they walked further); the time it took them to climb and descend stairs; the time it took them to lift and carry 10 pounds; and the time it took them to get in and out of a car. In the weight-lifting, group, there was an 8% lower score on the physical disability questionnaire, 8% lower pain score, greater distance on the six-minute walk, and faster times on the lifting and carrying task and the car task than in the individuals in the study who did not exercise.
