I mean, without the need of steroids

Men generally build muscle faster than women because of differences in hormones. Testosterone, which men have more of, plays a big role in muscle growth. It helps muscle fibers grow larger and recover quicker after workouts. Women have less testosterone, so their muscle growth tends to be slower and more gradual. It’s not about anyone being better or worse and just different biology at work.

Because men have more muscle. Women can still build crazy muscle but it’s just much easier for men

Wow there is a lot of misinformation in this thread. Actually, proportionally, women grow muscle at the same rate as men (about 0.1-0.2% of starting muscle mass per session). Testosterone’s biggest effect (within normal ranges) appears to be on untrained muscle mass. Women start with lower test, therefore start with lower muscle mass, therefore absolute growth is slower, and their max is lower. Once you reach an adult, you have a given number of muscle fibres, you can enlarge those fibres, but you can’t increase the number of fibres. Which ultimately determines your peak. Once special supplements enter the mix, all bets are off. We don’t really know why there’s such a huge variance in responses to steroids. Ultimately, hormone interactions are extremely complicated and not entirely understood. For example, estrogen is extremely hypertrophic. Men with low estrogen levels will see lower gains, but you still hear bros talk nonsense about phytoestrogens in soy etc. In short, I wouldn’t recommend reddit as a place to research this topic.

Testosterone is classified as a performance enhancing drug that is banned specifically because it makes it way easier to build muscles. Men naturally have much more testosterone than women. Aka, we naturally produce a performance enhancing drug. Which is a good part of why sports tend to be divided by sex. Men have a built in unfair advantage in terms of muscle mass.
