I kind of want to start writing again, but I’m not really sure what.  Any ideas?

Two or more ladies competing obsessively to grow larger over a period of time is always a hit with me

I'm always fond of FMG stories.

A mother becoming a bodybuilder with support from her family especially her son

1. Young wife with some medical condition that causes her masculisation like muscle growth, body hair growth, clit growth, voice deepening, but in slow pace and without characters change. The couple do not like these changes, but they have to used to it and in the end they found they like it.

2. Husband gives his young wife steroids in secret that causes her masculisation like above. She do not like it, but husband keeps feeding her with steroids and tries to convince her that these changes are awsome.

hi.

A guy is hired in a female gym to do the maintenance and he realizes that even the weaker girl is stronger than him.

A guys best friend starts dating his dream woman and he gets to see her up close many times and hear stories. A guy and his friends all have a martial arts fetish and get together to share videos etc...It all changes when a lady opens a dojo in town and fulfills their fantasies. A single bodybuilder mom moves to town and a guy meets her and gets to experience her incredible strength as they get to know each other and date.

One more, a married muscle mom moves in next door to a guy and his family. He struggles with his attraction to her.

The current best female bodybuilder in the world wants to show that she can also compete against men and begins a life of hard training, posing and wrestling against male.

Experimental muscle growth tonic accidentally gets out of lab and into the general public. Older women(late 40’s, 50’s and early 60’s get some by accident at local drug store, thinking it would help like vitamins but causes instantaneous muscle growth and wild sexual urges to the nearest man.

1. Cute, petite girl is locked in a room with only a bed, a small but seperate bathroom with mirror and a small set of weights. Food is dropped periodically through a small elevator shaft. No windows, she can only peek thru the doorknob. Tries bangging at the wooden door a few times but no one answers. She ignores the weights at first but eventually becomes so bored that she decides to try out the weights. Does random exercises then one day sees some results at the bathroom mirror. Decides to lift more until one day she tries to bang at the door again and finds out that she can damage it slightly now. Eventually breaks the door down only to reveal a bigger set of weights now complete with suppletments and workout books. Door is now made of metal. You get the idea.

2. Girl discovers her crush has a muscle fetish. Works out for a long time until she gets a body that even guys would be envious of (solid flat pecs type). People occasionally mistake her for a hot guy when she wears tight shirts and a cap. Crush now has a girlfriend, girl decides to steal his girl by dressing up as a guy. Gets news that the couple will be going to a pool party. She even goes as far as walking topless at a party just to seduce the girlfriend.

3. Girl is a die hard cosplay fan. She can dress up as pretty boy characters but also wants to achieve characters like goku from dragon ball. Works out like crazy and eventually gets the body for the said character. Looks at the mirror and is turned on by her own body since she looks like a macho guy when in costume. Proceeds to try out different characters and does a photoshoot with her photographer friend. Posts pics on social media and becomes a star.

 Marooned on a lush jungle world with high gravity, a colony ship is at the mercy of its mission A.I. as it realises that men need to remain strong, but light enough to hunt in the trees while the women need to be strong enough to protect the colonists from wild massive predators that roam the jungle floor. Some colonists lean in, some try to back out.

Anything resembling work by poddy90/dickarus or thesabre

Hi there! How about LitRPG in fantasy setting, where girl gets a class that gives her perks and skills to make her muscles bigger, harder and stronger. And she fights using them and her bare fists

Women who are confident and assertive of their strength are always a hit with me.
