What are the best ways to improve SMV? Gym, looksmaxxing (don't mean corny tips just basic ones).

Lose the excess bodyfat, get a 6pack.

This is far and away the best way to be sexually attractive

Getting lots of money.

This does not contribute to sexual market value

I'm asking just to have something other than the gym which will take for me atleast 1 year to have a decent physique.

You said "improve". No excuses. Lose the bodyfat.

Any other useful tips or habits I should indulge in?

Learn to talk and charm people. You can make huge gains in a few weeks with focused effort.

Stop being a fat cunt and get to the fucking gym

Read the side bar.

1.Getting fit 2.Having a passion,a hobby,something you love to do 3.Having a career,good economic standing, stable job,able to provide 4.Having a ton of money, enough to burn

1. Not leading with your wallet, women will see that with their third eye and take advantage of you,probably never becoming emotionally available or not being able to pair bond with you cause you're just their bank boy 6.Having a strong frame, enough for her to notice it and wanting to be in your frame where she will feel the most feminine,loved and secure 7.Learning game,getting women.Women love a man that just "gets" it/her 8.The usual,if you can't be attractive don't be unattractive

Seconding @MrSupreme Other than the obvious gym and money - become interesting, have something valuable to say: read books (not self help bs but actual literature: Dostoyevsky, Sartre, etc), have hobbies.

Also, and some will disagree with me, invest into combat sports (boxing, wrestling, MMA - anything), because a good physique, on a man that can’t put it to use, is worthless. If your country allows concealed carry - learn how to shoot, learn as much as you can about guns and ammo. Become dangerous - not a wolf, but a shepherd-dog.

Firstly, have you read the sidebar? Besides lifting weights (which gives the most bang for your bucks), there's being assertive, being charming, having preselection and social proof, and being socially calibrated.

looksmaxxing

The "maxx" suffix is usually a tell of someone who has read too much incel/ blackpill stuff. You don't have to "max" jack shit, and are far better off being well-rounded. I've discussed this before many times on the trp.red side of the site: example 1 and example 2. There's more, but I'm getting too short on time to dig much deeper.

which will take for me atleast 1 year to have a decent physique.

You're likely to see positive results a lot sooner than that. Within 3-4 months, most people will look at you different and treat you different.

[other posters talking about money]

By all means, make money for yourself, but don't go thinking it raises your SMV. provisioning is a beta trait, and so this raises your RMV/MMV rather than your SMV. I strongly advise against flaunting money to attract women. You'll only attract manipulative, gold-digging whores.

Go through the sidebar, especially anything from Roissy/Heartiste and Roosh. Practice the game they teach until it becomes easy for you. Too much reading without any practice and experience can end up doing more harm than good.
