=== Assistant: Great question! ===
Great question! The average woman generally has less muscle mass and strength than the average man, primarily due to differences in hormones, body composition, and muscle distribution. Here’s a breakdown with rough numbers and key differences:

===== - Testosterone is the main hormone driving muscle growth. Men typically have 10–20x more testosterone than women. =====
* Estrogen in women promotes fat storage rather than muscle growth.

===== - Muscle mass (total body): - Men: About 40–45% of body weight is muscle. - Women: About 30–35% of body weight is muscle. =====

So, women generally have about 60–75% of the muscle mass of men (depending on body size, training status, and other factors).

===== - Upper body strength: - Women have about 40–60% of men’s upper body strength. - This gap is larger due to men having more upper body muscle and broader shoulders. =====
* Lower body strength: - Women have about 70–75% of men’s lower body strength. - The gap is smaller here because women tend to carry relatively more muscle in the legs and hips.
* Absolute strength: - On average, women are about 50–60% as strong as men in total-body strength, untrained. - When normalized for lean body mass, women can be around 85–90% as strong as men in some lifts, especially in the lower body.

===== - Men tend to have larger Type II (fast-twitch) muscle fibers, which are more powerful. =====
* Women often have better muscular endurance and fatigue resistance due to more oxidative (Type I) muscle fibers.

Let me know if you want comparisons for trained athletes, hormonal effects (e.g., TRT, menopause), or anything deeper!
