Strength Training
Strength training, also known as resistance training, plays a significant role in reducing the risk of developing heart disease, cancer, type 2 diabetes, and neurodegenerative diseases by:
- Improving Metabolic Health and Insulin Sensitivity. Strength training is highly effective in improving insulin sensitivity and glucose metabolism, which are crucial for preventing and managing type 2 diabetes. By increasing muscle mass and reducing body fat, strength training helps in regulating blood sugar levels. Muscles, when engaged in resistance training, use glucose more efficiently, which can lower blood sugar levels and reduce the strain on the insulin-producing cells in the pancreas [1].
- Enhancing Cardiovascular Health. While typically associated with aerobic exercises, strength training also benefits heart health [2]. It can help lower blood pressure, improve cholesterol levels, and reduce the risk of arterial stiffness and endothelial dysfunction, all of which are risk factors for heart disease. By strengthening the muscles, including the heart, resistance training enhances overall cardiovascular efficiency [3].
- Reducing Inflammation and Oxidative Stress. Chronic inflammation and oxidative stress are underlying factors in the development of many chronic diseases, including certain types of cancer and neurodegenerative diseases. Strength training can help reduce inflammation and oxidative stress in the body. It stimulates the release of anti-inflammatory cytokines and helps in the production of antioxidants. These factors contribute to a reduced risk of cancer and may also play a role in slowing the progression of neurodegenerative diseases by protecting brain cells from damage [4].
Furthermore, strength or resistance training is essential for maintaining muscle mass, which tends to decline with age. Building muscle supports metabolic health, strengthens bones, and can help prevent injuries. Engage in muscle-strengthening activities that target all major muscle groups at least twice a week can be instrumental in prolonging healthspan by preserving physical function [5].
Aerobic Exercise Increases Longevity
Aerobic exercise is fundamental to any longevity-focused fitness regimen. Activities such as walking, running, swimming, and cycling increase your heart rate and respiration, improving cardiovascular health and respiratory function. The American Heart Association recommends at least 150 minutes of moderate aerobic exercise or 75 minutes of vigorous exercise per week to reap the benefits, which include a reduced risk of chronic diseases and an improved healthy life expectancy [6].

Aerobic exercise is highly effective in reducing the risk of heart disease, cancer, type 2 diabetes, and neurodegenerative diseases. It reduces these risks by:
- Enhancing Cardiovascular Health. Aerobic exercise is particularly beneficial for heart health [7]. It strengthens the heart muscle, improves blood circulation, and increases the efficiency of the cardiovascular system. Regular aerobic activity can lower blood pressure, reduce bad cholesterol levels, and improve heart function, all of which significantly reduce the risk of heart disease. This type of exercise also enhances the elasticity of blood vessels, reducing the risk of atherosclerosis.
- Improving Metabolic Function and Insulin Sensitivity. Aerobic exercise is effective in controlling blood sugar levels and improving insulin sensitivity, which is crucial in preventing and managing type 2 diabetes [8]. It helps the muscles absorb glucose more efficiently, reducing the burden on the pancreas. Additionally, aerobic exercise can aid in weight management, a key factor in reducing the risk of developing type 2 diabetes.
- Reducing Inflammation and Supporting Brain Health. Regular aerobic exercise has been shown to reduce systemic inflammation, which is a contributing factor to many chronic diseases, including certain cancers. It also boosts the immune system, potentially lowering the risk of certain types of cancer. For neurodegenerative diseases, aerobic exercise increases blood flow to the brain, which can support the growth and survival of neurons, reduce the accumulation of toxic proteins linked to neurodegenerative diseases, and improve cognitive function [9].
Anaerobic Exercise
Sprint interval training (SIT), a form of high-intensity anaerobic exercise, can significantly reduce the risk of heart disease, cancer, type 2 diabetes, and neurodegenerative diseases. SIT sessions involve short bursts of intense exercise followed by rest and are particularly beneficial for those looking to achieve health benefits in shorter workout durations. This activity supports longevity by:
- Enhancing Cardiovascular Efficiency and Heart Health. Despite being an anaerobic activity, sprint interval training has profound effects on cardiovascular health. It improves the heart’s efficiency and capacity by increasing its volume and strengthening the cardiac muscles. This leads to better blood circulation and oxygenation of the body, which can lower the risk of heart disease. SIT has also been shown to improve blood vessel function and increase the elasticity of arteries, reducing the risk of atherosclerosis. Crucially, SIT leads to improvements in VO2 Max, which is one of the strongest predictors of all-cause mortality and cardiovascular health [10].
- Improving Metabolic Function and Insulin Sensitivity. SIT is highly effective in enhancing metabolic rate, which aids in better glucose regulation and insulin sensitivity [11]. This is particularly beneficial for the prevention and management of type 2 diabetes. By promoting rapid and intense muscle contractions, SIT causes muscles to use glucose more efficiently, lowering blood sugar levels. Additionally, the afterburn effect (excess post-exercise oxygen consumption or EPOC) of SIT means that the body continues to burn calories at an elevated rate even after the exercise session, aiding in weight management and metabolic health.
- Boosting Brain Health and Cognitive Function. High-intensity interval training like SIT has been linked to improved brain health and cognitive function [12], which are important in reducing the risk of neurodegenerative diseases. SIT increases the production of brain-derived neurotrophic factor (BDNF), a protein that plays a key role in neuron survival and growth. Increased BDNF levels are associated with improved memory, learning, and overall brain function. Additionally, the increased blood flow to the brain during intense exercise can contribute to the health of brain cells and potentially delay the onset of neurodegenerative diseases.
Balance Training
As we age, balance can deteriorate, which not only leads to a greater risk of falls but also increases all-cause mortality [13]. Incorporating strength-related balance exercises into your routine is an effective strategy to enhance proprioception and stability.
An overlooked aspect of balance training is its role in reducing the risk of heart disease, cancer, type 2 diabetes, and neurodegenerative diseases by:
- Preventing Falls and Related Injuries. Balance training is crucial in enhancing stability and coordination, which becomes increasingly important with age [14]. By preventing falls, it indirectly reduces the risk of injuries that could exacerbate heart conditions or lead to a sedentary lifestyle, which is a risk factor for type 2 diabetes and some cancers. Maintaining physical activity through balance helps in overall cardiovascular health and metabolic function.
- Improving Muscle Strength and Joint Health. Balance exercises often involve the strengthening of muscles and joints [15]. Stronger muscles and healthier joints contribute to better overall physical health, which can indirectly affect heart health and metabolic function. Improved muscle mass can enhance insulin sensitivity, reducing the risk of type 2 diabetes, and muscle activity can help in maintaining a healthy weight, a key factor in cancer prevention.
- Supporting Cognitive Function and Neurological Health. Balance training requires the integration of multiple sensory inputs and motor coordination, which stimulates various parts of the brain [16]. This stimulation can contribute to better brain health and may help in delaying the onset or progression of neurodegenerative diseases. Additionally, maintaining physical activity through balance exercises can improve overall mental well-being and cognitive function, which are important in the context of neurodegenerative diseases.

Flexibility Training
Flexibility training, which includes exercises that improve the range of motion of muscles and joints, also plays a significant role in reducing the risk of heart disease, cancer, type 2 diabetes, and neurodegenerative diseases by, for example:
- Reducing Arterial Stiffness through Enhanced Circulatory Health. Flexibility exercises, particularly stretching, play a crucial role in improving the elasticity of blood vessels, including arteries [17]. Arterial stiffness is a significant risk factor for heart disease, as it can lead to impaired blood flow and increased strain on the heart. Regular stretching helps in maintaining and improving the flexibility of the arterial walls, which enhances overall blood circulation. This improved arterial health facilitates the efficient delivery of oxygen and nutrients to various tissues, including the heart, and aids in the efficient removal of waste products. By reducing arterial stiffness, flexibility training thus contributes significantly to cardiovascular health and lowers the risk of heart disease.
- Reducing Stress and Inflammation. Regular flexibility training can be effective in reducing stress and tension in the body. Stress and chronic inflammation are risk factors for many chronic diseases, including heart disease, certain types of cancer, and possibly neurodegenerative diseases. By alleviating stress and potentially lowering inflammation, flexibility exercises can play a role in reducing the risks associated with these conditions [18].
- Improving Glucose Metabolism. Flexibility training may have a positive impact on glucose metabolism, which is crucial in the prevention and management of type 2 diabetes [19]. By enhancing muscle and joint function, these exercises can lead to more efficient movement and potentially better glucose utilization in the muscles, contributing to improved insulin sensitivity and better blood sugar control.
Flexibility exercises help maintain joint range of motion, which is crucial for daily activities and overall mobility. Integrating flexibility training, such as stretching or yoga, into your schedule at least twice a week can decrease joint discomfort and help preserve your functional abilities, contributing to a longer healthspan [20].
