One has to work at it!
For most of us these days old age is part of the scene (and I am classifying old age as being over 70 years). Here are a few facts from the website of the World Health Organization.
Key facts
- Worldwide obesity has nearly tripled since 1975.
- In 2016, more than 1.9 billion adults, 18 years and older, were overweight. Of these over 650 million were obese.
- 39% of adults aged 18 years and over were overweight in 2016, and 13% were obese.
- Most of the world’s population live in countries where overweight and obesity kills more people than underweight.
- 39 million children under the age of 5 were overweight or obese in 2020.
- Over 340 million children and adolescents aged 5-19 were overweight or obese in 2016.
- Obesity is preventable.
What are obesity and overweight Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health.
Body mass index (BMI) is a simple index of weight-for-height that is commonly used to classify overweight and obesity in adults. It is defined as a person’s weight in kilograms divided by the square of his height in meters (kg/m2).
Adults
For adults, WHO defines overweight and obesity as follows:
- overweight is a BMI greater than or equal to 25; and
- obesity is a BMI greater than or equal to 30.
BMI provides the most useful population-level measure of overweight and obesity as it is the same for both sexes and for all ages of adults. However, it should be considered a rough guide because it may not correspond to the same degree of fatness in different individuals.

Now this is not a post about obesity or being overweight. It is a post taken from The Conversation about staying as healthy as one can in one’s older years.

Steep physical decline with age is not inevitable – here’s how strength training can change the trajectory
Zachary Gillen, Mississippi State University
Raise your hand if you regularly find yourself walking up a flight of stairs. What about carrying heavy bags of groceries? How about picking up your child or grandchild? Most of us would raise our hands to doing at least one of those weekly, or even daily.
As people age, it can become more and more difficult to perform some physical tasks, even those that are normal activities of daily living. However, prioritizing physical fitness and health as you get older can help you go through your normal day-to-day routine without feeling physically exhausted at the end of the day.
It can also help you continue to have special memories with your family and loved ones that you might not have been able to have if you weren’t physically active. For example, I ran two half-marathons with my dad when he was in his 60s!
I am an exercise physiologist who studies how people can use resistance training to improve human performance, whether it be in sports and other recreational settings, in everyday life, or both. I am also a certified strength and conditioning specialist. My career has given me the opportunity to design exercise programs for kids, college athletes and elderly adults.
Staying physically active as you get older doesn’t need to include running a half-marathon or trying to be a bodybuilder; it could be as simple as trying to get through the day without feeling winded after you go up a flight of stairs. Although our muscles naturally get weaker as we age, there are ways we can combat that to help improve quality of life as we get older.
Muscle loss and chronic disease
One of the most important parts of exercise programming, no matter who I am working with, is proper resistance training to build muscle strength. Some amount of age-related loss of muscle function is normal and inevitable. But by incorporating resistance training that is appropriate and safe at any ability level, you can slow down the rate of decline and even prevent some loss of muscle function.
The medical term for a condition that involves age-related loss of muscle function and mass is sarcopenia. Sarcopenia can begin as early as age 40, but it tends to be more common in adults age 60 and older. Sarcopenia is associated with a number of health issues such as increased risk of falling, cardiovascular disease and metabolic disease, among others.
In one of our team’s previous studies, we saw that otherwise healthy individuals with sarcopenia had issues delivering vital nutrients to muscle. This could lead to greater likelihood of various diseases, such as Type 2 diabetes, and slow down recovery from exercise.
Recent estimates suggest that sarcopenia affects 10% to 16% of the elderly population worldwide. But even if a person doesn’t have clinically diagnosed sarcopenia, they may still have some of the underlying symptoms that, if not dealt with, could lead to sarcopenia.
Strength training is key
So the question is, what can be done to reverse this decline?
Recent evidence suggests that one of the key factors leading to sarcopenia is low muscle strength. In other words, combating or reversing sarcopenia, or both, may be best done with a proper resistance-training program that prioritizes improving strength. In fact, the decline in muscle strength seems to occur at a much faster rate than the decline in muscle size, underscoring the importance of proper strength training as people age.
Continuing to regularly strength train with moderate to heavy weights has been shown to be not only effective at combating the symptoms of sarcopenia but also very safe when done properly. The best way to make sure you are strength training properly is to seek out guidance from a qualified individual such as a personal trainer or strength and conditioning specialist.
Despite the clear benefits of strength training, it’s been shown that only about 13% of Americans age 50 and older do some form of strength training at least twice a week.
Finding what works for you
So how does a person properly strength train as they age?
The National Strength and Conditioning Association, a leading organization in advancing strength and conditioning around the world, states that for older adults, two to three days per week of strength training can be incredibly helpful for maintaining healthy muscle and bone and combating a number of chronic conditions.
The organization recommends that these workouts involve one to two exercises involving multiple joints per major muscle group, with six to 12 repetitions per set. These are done at an intensity of 50% to 85% of what’s known as one-repetition maximum – the most weight you could handle for a single repetition – with the exception of body weight exercises that use one’s own body weight as the resistance, such as pushups.
I would also recommend resting for about two to three minutes between sets, or even up to five minutes if the set was challenging. For older adults, particularly those age 60 and older, the National Strength and Conditioning Association guidelines suggest that a program like this be performed two to three days per week, with 24 to 48 hours between sessions.
An example of a strength training routine for older adults based on the National Strength and Conditioning Association guidelines
There are a great variety of exercises that could be done interchangeably in a strength training program like this.
| Exercise | Number of sets | Repetitions per set | Intensity |
|---|---|---|---|
| Barbell squat | 3 | 6 | 70-85% |
| Barbell bench press | 3 | 6 | 70-85% |
| Dumbbell lunges | 3 | 8 per leg | 50-70% |
| Dumbbell bent over row | 3 | 10 | 50-70% |
| Double-leg hops | 2 | 12 | Body weight |
| Pushups | 2 | 12 | Body weight |

Making life’s tasks lighter
The guidelines above are only one example out of many options, but they provide a framework that you can use to build your own program. However, I would highly recommend seeking out a professional in the field to give specific exercise programming advice that can be tailored to your own needs and goals as you age.
Following such a program would give your muscles an excellent stimulus to enhance strength, while also allowing enough recovery, a very important consideration as people age. You might think it looks like a huge time commitment, but an exercise routine like this can be done in less than an hour. This means that in less than three hours of strength training per week you can help improve your muscle health and reduce the risk of getting sarcopenia and associated health issues.
It’s also important to note that there is no one right way to do resistance training, and it needn’t involve traditional weight equipment. Group classes like Pilates and yoga or those that involve circuit training and work with resistance bands can all produce similar results. The key is to get out and exercise regularly, whatever that entails.

My wife, Jean, was diagnosed with Parkinson’s Disease (PD) in December, 2015. Many of you know that.
Fortunately at our local Club Northwest there was a group of PD sufferers who twice a week held a ‘Rock Steady Class’ under the instruction of a professional coach; Jean joined the group. It was a brilliant move for Jean and she gets a huge amount of care from being with them.
Luckily for me having to drive Jean into Club Northwest it made sense for me to sign up to a fitness class at the same time so I am put through a regular fitness routine under the coaching of Bruce. Plus I try and go bike riding three times a week.
In other words, we both try and stay as fit as we can.
