Reasons the latest research says everyone should do strength training …

Strength training isn’t just for bodybuilders or professional athletes, it’s a vital practice for anyone who wants to improve their physical fitness, mental health, and brain health. While it’s often overlooked in favor of aerobic exercises like running or cycling, the latest research reveals that incorporating resistance training into your fitness routine is one of the most powerful ways to enhance your overall well-being. Whether you’re in your 20s or 70s, strength training can help you build muscle, boost your mental health, and protect your brain from age-related decline.

Fitness Benefits: Enhanced Strength, Muscle Mass, and Performance.
Strength training is foundational for building and maintaining muscle mass, which directly affects strength, endurance, and overall fitness. Muscle mass naturally declines as we age, a process known as sarcopenia. A 2023 study published in the Journal of Applied Physiology found that resistance training (such as weightlifting) prevents or even reverses this loss, keeping muscles strong and functional well into older adulthood.

Strength training has been shown to improve athletic performance, not just for athletes but for anyone engaging in physical activity. According to a 2022 study in Sports Medicine, resistance training enhances power, agility, and coordination, making everyday movements — like lifting groceries, climbing stairs, or playing sports — easier and more efficient. Even moderate strength training can improve performance in other fitness areas, such as aerobic capacity and balance, helping individuals stay fit and active.

Strength training is also incredibly effective for boosting metabolism. The International Journal of Obesity published a 2022 study highlighting how regular strength training increases resting metabolic rate (RMR) by promoting muscle growth, which requires more energy at rest. This boost in metabolism contributes to fat loss and improved body composition. The impact on body composition is significant, with a study in Obesity Reviews showing that strength training can reduce visceral fat (the harmful fat around internal organs), even without significant changes in diet.

Mental Health Benefits: Reducing Anxiety, Depression, and Stress.
Strength training offers profound mental health benefits, with research suggesting that it can reduce symptoms of anxiety, depression, and stress. A 2023 meta-analysis published in JAMA Psychiatry examined 33 randomized controlled trials and found that strength training significantly improved mood and reduced symptoms of anxiety and depression. This is especially beneficial in today’s world, where mental health struggles are on the rise.

The mechanism behind this is believed to be related to the release of endorphins, the body’s natural “feel-good” chemicals, which are triggered by physical exertion. A 2021 study published in Frontiers in Psychology found that strength training was just as effective as aerobic exercise in treating anxiety and depression, offering an accessible and time-efficient way for individuals to manage mental health.

But it’s not just about mood improvement in the short term. Strength training has been shown to have long-lasting effects on mental resilience. A 2022 study in Psychology of Sport and Exercise found that people who regularly engaged in strength training had lower levels of perceived stress and greater emotional regulation. This was especially evident in individuals dealing with chronic stress or a history of trauma.

One of the most compelling aspects of strength training for mental health is its ability to foster a sense of accomplishment and control. Setting goals, achieving progressive overload, and witnessing physical changes can increase self-esteem and confidence, which in turn combats feelings of helplessness often associated with mental health disorders.

Brain Health: Cognitive Function, Memory, and Neuroprotection.
Strength training isn’t just good for your muscles, it’s good for your brain, too. One of the most exciting areas of recent research is the impact of strength training on cognitive function and brain health. A 2021 study published in The Journals of Gerontology found that older adults who engaged in resistance training showed significant improvements in cognitive performance, including better memory, attention, and executive function (the brain’s ability to plan, problem-solve, and multitask). These benefits were especially important for older adults, as resistance training can slow the progression of age-related cognitive decline.

Furthermore, strength training has been shown to increase levels of brain-derived neurotrophic factor (BDNF), a protein that supports neuroplasticity – the brain’s ability to form and reorganize synaptic connections. This is crucial for learning, memory, and the overall maintenance of cognitive function. A 2022 study published in Neurobiology of Aging found that regular resistance exercise in older adults increased BDNF levels, which in turn enhanced brain function and helped protect against neurodegenerative diseases like Alzheimer’s.

But the cognitive benefits of strength training aren’t just for older adults. In a 2023 study published in Frontiers in Aging Neuroscience, young adults who performed regular strength training had improved cognitive flexibility, an essential cognitive skill for adapting to new situations and solving problems. The study also found that strength training contributed to better focus and sustained attention, skills that are often compromised under stress or in individuals with mental health challenges.

Strength training has been shown to help increase gray matter volume in the brain, particularly in areas responsible for motor control and executive function. A study from NeuroImage in 2021 revealed that individuals who regularly engaged in strength training had greater gray matter density in the prefrontal cortex — the area of the brain associated with decision-making, impulse control, and complex cognitive behaviors. This suggests that strength training may play a role in improving overall brain health and function.

Synergy Between Fitness and Mental Health.
The connection between physical fitness and mental health is clear, but the benefits of strength training go beyond simple mood improvement. Studies show that engaging in regular resistance training has a synergistic effect on mental well-being. In a study published in Clinical Psychological Science in 2022, individuals who strength-trained reported fewer symptoms of depression and anxiety compared to those who only engaged in cardio exercise or had no exercise regimen at all. Researchers concluded that strength training may have a unique capacity to promote emotional resilience and psychological well-being, likely due to both the physiological benefits (like increased endorphins) and the psychological aspects of setting and achieving personal goals.

Additionally, strength training enhances the body’s ability to handle stress. A 2023 study in Psychoneuroendocrinology found that participants who engaged in strength training experienced a lower cortisol response (the stress hormone) during stressful situations compared to those who didn’t engage in resistance training. This suggests that strength training not only improves mental health but may also help individuals build greater stress tolerance.

Strength training offers a practical method to not only build physical strength but to create a lasting impact on your mental and cognitive health. The discipline and effort you invest in each session strengthens more than your muscles; it sharpens your mind and helps stabilize your emotions. This holistic practice supports you through life’s pressures, enhancing your ability to focus, manage stress, and navigate the demands of daily life. As you continue to train, you’re developing a foundation of mental and physical resilience that pays off in the way you feel, think, and respond to challenges.
