A personal trainer emphasizes that achieving a lean physique hinges on body fat percentage and overall body composition, rather then solely on cardio. The ratio of fat to muscle dictates how lean an individual appears.
To build lean muscle mass and reduce body fat, resistance training is prioritized. Cardio is incorporated on separate days for clients who enjoy it, wiht an encouragement to maintain a consistent daily step count.
Lean muscle tissue is more metabolically active than fat tissue, meaning a higher muscle mass leads to a better resting metabolic rate and increased calorie expenditure, even at rest. Muscle growth requires important energy.
Many individuals focus on cardio for fat loss due to its impact on the daily energy deficit (energy intake versus energy expenditure). However, cardio is not as effective for building or maintaining muscle.Resistance training is crucial for bone and joint health, preserving muscle mass as one ages, and consequently boosting daily energy expenditure through muscle maintenance and growth.
It’s significant to critically evaluate research, acknowledging potential design flaws and exclusions in studies. A balanced approach that considers lifestyle factors such as sleep, stress, and diet is essential for overall health and happiness.
