Ok, I'm almost convinced to start lifting weights... if they release a study showing hair growing I'll be 100% in.

Why so snarky? Those two do not contradict eachother
There’s this remarkably stupid stereotype that muscles equates to stupidity. If you look at some of the champions, they all have degrees in fields like Accounting (Ronnie Coleman, Phil Heath) or Chemistry (Frank Zane). Schwarzenegger famously did business school at night while a bodybuilder.

#55Earlier quoted context omitted.
I've had a lot of fights about this with my girlfriend. We both work in academia and regularly go to the gym, but she insists to have a drink every now and then, which she says helps her take an edge off work stress. She also scolds me some times when I want to go to bed before 10pm, saying this is too restrictive and less fun. We ended up breaking up last week - not exclusively because of this, but these incompatibi…
In this scenario, I am your girlfriend, and you are my boyfriend (or from my perspective you are my wife ). For what it’s worth, I’ve found that if I try to go to bed too early — as my wife often insists — I wake up in the middle of the night. This happens constantly enough that I really try to avoid being in bed before 11pm.
Everybody is different. The reason I need to go to bed early is that I wake up before 7am every day, regardless of when I go to bed. So the only way for me to get 8-9 hours of sleep is to go to bed early.
Your body is different from mine so you need a different routine. My point was that it's important for me to maintain a certain schedule which was incompatible with my partner - which is fair enough.

#56Muscles need neurons to control them, so it makes sense that some feedback loop would exist. I remember reading about similar feedback loops between muscle growth and bone density (as you get stronger, bones benefit from being resilient to higher loads). As I understand it, the kinetic chain goes nervous system -> muscles -> tendons -> bones. It would make sense for all of these to make each other stronger in some wa…
It makes sense to think of bones as endocrine organs.

#57Everyone who starts working out notice this. Very fast gains in strength and resistance the first weeks due to neuronal signals improvement. And then a slow down where muscle gains take over.
Muscles are lazy, CNS is necessarily much much lazier.

#59Clarification since a number of the comments are reading this as "strength training makes your brain stronger". This study looked at _motor_ neurons, not neurons in your brain. Motor neurons are the neurons between your spinal cord and muscle cells, responsible for transferring the signal from your brain to contract/relax your muscles.
I think it was already known that working out muscles increases the innervation (the resolution of how many neurons are attached to a muscle) of the muscles, which is the mechanism for increased motor control that eg pianists have. I think this study is shedding more light on process, and providing stronger empirical evidence for that exact mechanism. Very exciting that this might be used to help people recover from nerve damage/spinal cord injury!

There is no negative effect to doing so, why would you not?
There's all kinds of potential negative effects.
1. It generally comes at non-zero financial expense.
2. I might not know what I'm doing.
3. I might get hurt.
4. I might cause someone else to get hurt.
Or, perhaps most-tortuously:
5. They're all going to laugh at me.
