Strength Training and Your Health

Strength training is crucial for good health. A regular strength training routine has been shown to benefit your:

  • Cognitive health.
  • Bone health.
  • Muscle health.
  • Independence.
  • Quality of life.
  • Longevity.

Some people refer to strength training as resistance training or weightlifting. We will use all three terms throughout this guide.

If you do not regularly strength train, you will begin losing as much as 3% of your muscle mass per year. Many are surprised to know that muscle loss starts in the mid-’30s. The older we get, the faster the rate of muscle loss. The expression “use it or lose it” applies very well to our muscles and bones.

Strength training is the solution, and it is available to each of us. It improves the strength of our muscles, bones and our retirement options!

Leading health organizations recommend strength training for older adults. Adding resistance training exercise to your weekly routine goes far beyond your muscle and bone health.

How Strength Training Benefits Your Bones

Strength training for osteoporosis is critical if you want to age with strong bones. This class of exercise has been shown to protect your bones in the following ways:

  • Lessens bone loss by suppressing the osteoclast activity level. (1)
  • Improves bone building by stimulating the osteoblast cells and the pre-osteoblast cells. (1)
  • Improves bone strength by making the bone more resilient to strains. (1)
  • Helps prevent falls. (2,3)
  • Protects your spine from degenerative changes, including compression fractures. (4)
  • Accelerates healing and recovery after a fracture. (5,6)
  • It improves your chances of returning to independence one year after a hip fracture. (7,8)

In the video below, I explain how strength training improves bone health and increases bone density.

Strength Training Lessens Bone Loss

Does strength training reduce bone loss? Strength training for osteoporosis can help lessen bone loss by providing stress to the bones. Gradual, progressive strength training stimulates the production of new bone. 
 
The process of bone remodelling is ongoing. Through strength training, we can slow the rate of bone loss and, in some cases, even reverse it.

Strength Training for Osteoporosis

Strength training can help maintain or increase muscle mass. When you lift a heavy load, more muscle fibres are recruited. Some muscles attach directly to bones, while others attach via tendons.  (As illustrated in the image below.) The contracting muscle sends mechanical signals to the bone. This mechanical signalling stimulates osteoblasts (bone-building cells) and calms the osteoclast activity (bone-cutting/cleaning cells). (1)

Strength Training for Muscle and Balance

As we age, we lose muscle mass and muscle-nerve connectivity. Both lead to weaker muscles. Weaker muscles produce weaker muscle contractions and weaker bones. This, in turn, increases our risk of falls and fractures. Strength training can help slow down muscle loss and preserve muscle mass. All of this can be delayed with strength training.
 
Strength training also helps improve balance, coordination, and overall fitness levels.  These fitness parameters help reduce the risk of falls and fractures. (2, 3)

How Often Should You Strength Train for Osteoporosis?

Leading health organizations, such as the National Strength and Conditioning Association and the American College of Sports Medicine, recommend strength training exercises at least twice weekly. They suggest that you target all major muscle groups. 
 
As we age, most of us do not have the energy to do all major muscle groups on the same day.
 
My clients over the age of 50 find it much easier to either do shorter routines daily or three times a week.  
 

This is how I designed the exercise schedules in my book, Exercise for Better Bones, and the Stronger Bones, Stronger Body Video streaming series

Examples of strength training exercises for an active adult include squats, lunges, push-ups, and modified back extensions. Start with a manageable weight.  Increasing the weight and intensity over time allows you to build muscle and bone safely.   

Strength Training for Osteoporosis, Osteopenia and Low Bone Density

Strength training exercises are beneficial for people with osteoporosis and osteopenia. Several major studies confirm this.

One of the most extensive studies specific to bone health began before the year 2000 in Germany.  Dr. Wolfgang Kemmler conducted a 16-year study of the benefits of exercise. His study focused on post-menopausal women with osteoporosis.

Dr. Kemmler found that post-menopausal women strengthened their muscles.  The same exercises could stop bone loss. (8)

A 2020 meta-analysis of the effects of high-intensity exercise on postmenopausal women. The study showed high-intensity exercise to be more effective for the spine than the hip. (9)

How Does Strength Training Prevent Osteoporosis and Osteopenia, and Increase Bone Density?

Strength training can help prevent osteoporosis and osteopenia. It increases bone density through remodeling.

Bone remodeling involves two major activities:

  • Resorption: Removing or resorbing old or damaged bone tissue.
  • Formation: Replacing it with new bone tissue. 

The balance between bone resorption and formation is vital for maintaining bone health. (11)

Unfortunately, things can get out of balance. After menopause, the resorption cells outnumber the formation cells. This can speed up bone loss and cause osteoporosis.

Strength training helps to inhibit the bone-resorbing cells and stimulate the bone-building cells. 

How Does Strength Training Differ from Weight Bearing Exercise?

Strength training involves the progressive loading of muscles. The goal is to fatigue them within 5 to 12 repetitions.

Weight bearing exercises usually involve more repetitions and a longer duration.  Activities such as running, brisk walking, basketball, and soccer are weight bearing.

Earlier, I mentioned exercise guidelines from leading organizations. These health organizations also recommend 30 minutes of aerobic activity daily. The aerobic activities can include weight-bearing exercises such as brisk-walking, running, or jumping-rope.

Both weight bearing exercise and strength training stimulate bone building. Whether you bear weight or strength train, your muscles vibrate. This vibration, in turn, pulls on the bone, stimulating bone growth.

Strength Training for Osteoporosis Products

I offer several strength training for osteoporosis products. The first product is my book, Exercise for Better Bones, and the other is a workout series in streaming video format.

Exercise for Better Bones

Exercise for Better Bones is a comprehensive exercise program for individuals who want to improve their bone health. It includes strength training exercise programs for people at different levels of fracture risk and activity level. Exercise for Better Bones is available on Amazon in print and Kindle format.

Stronger Bones, Stronger Body Video Workouts

Stronger Bones, Stronger Body is an online video series designed for people who want to follow me through a structured workout. 

Strength Training and Muscle-Nerve Communications

Our nerves’ ability to send messages to muscles decreases as we age. But it need not be the case. Strength training improves the nerves’ ability to talk to muscles.

In 2021, Dr Walker reviewed evidence from studies of resistance training-induced neural adaptation in older adults. (11)

A 2022 study further supported the positive effect that intense strength training could enhance muscle-nerve communication. The study included 38 healthy men in their late 60s and 70s. After just 16 weeks of heavy resistance exercise, there was evidence that increased nerves could communicate better with muscles. (12)

You’re Always Young Enough to Get Stronger

Researchers conducted a small study with healthy older adults over the age of 85. All individuals were living independently and the age ranged from 86 to 96 years old.

Eight weeks of strength training generated significant results. The residents added almost 10% muscle mass to their thighs and improved their strength by 174%. (13)

This study proved that you’re always young enough to make strength gains. You need not be competing in the Masters.

The Power of Protein When Strength Training

Protein is essential to building muscle and bones. At any age, protein is critical for supplying the amino acids necessary to build bone and muscle.

Around 50 years of age, we need to increase the protein in our diets to maintain muscle mass. Regular exercisers should eat more protein than the recommended daily intake of 1.0 to 1.2 g/kg of body weight. (14)

Most adults can generally meet this intake level through diet alone. But supplement as needed.

Consume protein within an hour of completing your strength training and with each meal throughout the day. 

The type of protein matters. In 2022, a study of 1,570 older men and women looked at this issue.  It found a positive association between animal protein and bone mineral density scores. (15)

In contrast, plant protein eaters had lower BMD scores.

Conclusion

The objective of this guide was to discuss the importance of strength training for osteoporosis and the role it plays in improving your bone health, reducing your risk of a fall and fracture, and helping you manage your osteoporosis, osteopenia and low bone density.
