Women generally have a higher percentage of body fat and less muscle compared to men due to their physical structure. While this characteristic may not pose significant issues in youth, as one ages, muscle loss can lead to various health problems.

First, muscles can only be maintained and increased through consistent use and strength training. In contrast, fat can accumulate without special effort, leading to a vicious cycle where muscle mass decreases and fat takes its place as one ages. In fact, it has been reported that women with low muscle mass and who neglect strength training lose an average of 1 kg of muscle every 10 years after the age of 35.

Second, muscle takes up less space than fat at the same weight, allowing individuals with more muscle to maintain a slimmer and more toned physique. Additionally, muscle is the area that consumes the most calories at rest, so having more muscle leads to a higher energy expenditure even when inactive, resulting in a body that is less prone to gaining weight.

Third, strength training greatly benefits bone health. Strengthening muscles and increasing joint flexibility can enhance bone density, effectively preventing osteoporosis. This is particularly important for women, as they are at greater risk of weakened bones as they age, making regular muscle maintenance crucial.

Fourth, muscles help regulate body temperature and boost metabolism, making one less sensitive to cold and heat, and aiding in overcoming fatigue and lethargy. Properly engaging in muscle-utilizing exercises improves blood circulation and activates metabolism, alleviating seasonal fatigue such as spring fatigue.

Finally, strength training contributes to enhanced immunity. The increase in body temperature from exercise improves immune function, and moderate exercise that induces sweating raises heart rate, facilitating the supply of oxygen and nutrients. These changes promote the activity of internal muscles and help strengthen the overall immune system.

We encourage you to apply the following insights to your exercise habits.

First, low-intensity muscle exercises are unlikely to yield significant results. Strength training requires pushing through the moments when you feel like giving up to see effects. In other words, sufficient strain on the muscles is necessary to stimulate muscle fibers, leading to increased muscle mass and strength.

Second, while it is challenging to lose fat from specific areas through targeted exercises, it is entirely possible to build muscle in those areas. Focusing on desired areas can develop the muscles there, resulting in a more toned physique.

Third, after the age of 30, it is crucial to strengthen the muscles that stabilize the body, such as the erector spinae, glutes, and thigh muscles. Maintaining strong erector spinae can prevent sagging of the abdomen and glutes, as well as hunching of the neck and shoulders, necessitating consistent exercise.

Fourth, timing plays a significant role in enhancing exercise effectiveness, particularly right after waking up and just before sleeping. Drinking a glass of cold water immediately upon waking can boost metabolic rate by 30%, aiding in energy expenditure and muscle gain. Additionally, developing a habit of stretching the entire body before bed can correct posture and maximize exercise benefits.

Finally, simply maintaining good posture can greatly enhance exercise effectiveness. It is advisable to always be conscious of your posture whether sitting or standing. When standing on public transport, keep your back straight and engage your calf and thigh muscles slightly to maintain balance. Also, when sitting, focus on engaging your core below the navel to ensure your weight is centered over your hips.

By understanding and practicing the fundamental principles of muscle training in daily life, you can significantly contribute to maintaining a healthy physique and improving overall physical health.
