【中高年の筋トレ】週2回15分でOK！科学が証明した「最小有効量」

You train hard every day, but you just end up feeling fatigued and your body shape isn't changing... This is for busy people in their 30s to 50s who have this problem. Based on the latest data from sports science, exercise physiology, and biochemistry (including systematic reviews and meta-analyses), this is a complete guide to the "Minimum Effective Dose" that will help you achieve maximum health benefits and physique transformation with minimal effort. Throw away outdated ideas like "push yourself to your limit," "aerobic exercise causes muscle loss," and "you should go to the gym every day" and discover the optimal, scientifically-based, and efficient solution to fitness.

Numerous meta-analyses support the effectiveness of "RIR (Repetitions in Reserve)," which does not push oneself to the limit, and the fact that combining it with aerobic exercise (concurrent training) improves health parameters. However, when it comes to extreme muscle growth among top athletes and professional bodybuilders, there is some debate regarding the need for some pushing and strategies to avoid the high-level interference effect. (For advanced exercisers, the most efficient way to build muscle is said to be 10-20 sets per week.) At this stage, there is no fully understood mechanism for predicting "individual differences in optimal frequency" due to individual recovery abilities and genetic background. Start with the "1-2 times per week, 30-60 minutes" recommended in this video, and monitor your own physical condition (autonomic nervous system fatigue, joint discomfort, etc.) and make fine adjustments accordingly.
