There are many ways to get money in SA...

Method 1.
Play the game normally

Method 2.
First you have your Drug dealing NPC these guys usually look like this
Killing these guys will grant you usually $2000-2500 and will always drop a Pistol
You find them mostly around the Gang areas of the map and little bit of the city
They are great source of Income to early game

Method 3.
Buy the house in Ballas territory called the Jefferson safe house
cost only $10,000 a couple of drug dealers should get you that no problem
Once purchased the house then save your game
Then go to the Inside track which is just west of your safe house
Now go inside and use the machine to max bet on the horse with the highest payout odd
The more money you have to bet the money you'll earn
Now watch the race and hope your horse wins.
If your horse doesn't win, then reload the save game until he does.

Method 4.
You old handy dandy Cheat Engine. That's right good old reliable.
If you don't want to the first method you can do this being the lazy way
This doesn't block the achievements at all
Anyways if you don't know how to use cheat engine then you don't need to read this

• 9. Go back ingame to see your new money. Congrats you were lazy to earn money and you don't have to grind for the rest of the game.

Once you pass the mission Drive-Thru
You will receive a call from Sweet saying you need to hit the gym

Honestly your stats are very low and you get short sprints and running time well heres a way to get rid of the hassle of running the tread mill and cycling at the gym without pressing anything

Download Key Presser
No Virus no installs it just a application

A link is here
https://sourceforge.net/projects/key-presser/


Once you download the program open it and set your settings in this image below


Go ingame to the gym and have CJ on the cycle on level 10, its gunna say for you to press the e button rapidly but you don't wanna key board warrior it

Back out go the program and start it, click back onto GTA SA and get out the menu and see CJ pedal on his own

Congratz keep doing this until hes max stamina

you can only workout so much each day so you would have to save until next day ingame has cycle, every save forwards the ingame time 6hrs so couple of saves should do the trick.

You can also do this method with the dumbbells and benchpress machine also

This method is easy to do, once you finish the mission The Green Sabre mission
You will be in the new region San Fierrrrrrrooooooooooo

And you will end up in this backwater little town called Angel Pine... there's is nothing to do in this town besides a couple of missions and one ammunition but guess what


this small town is the greatest method of getting your health bar double

Grab a paramedic van and start the sub mission
In this small town you are limited in the area to that town compare to the other regions

Once you start the mission you would have to pick up npc in the vehicle and drop them off at the clinc you can only hold up to 3 npc at a time so you have to drop them off consistly but the town is so small you have more than enough time to pick up the npcs. Finish the level and continue.

Rinse and repeat to complete the levels until you past level 12
You will see your health bar progress as you complete the levels.

Congratz you max out your health mid early game.

this is the most efficient method to raise your health and it is a speedrunning method

So Same thing as doing the Health trick is grab a fire truck from making a nearby fire or finding one from san fierro...

Get a firetruck make sure it has nozzle on top of the vehicle and start the mission in Angel Pine.
You won't go anywhere farther than whet stone or mount chillad

Making the trips super quick and easy... don't drive to crazy cause the handling on the truck ain't the best plus you'll have enough time to get to the fire spots.

Once completed you'll be finished in no time and never have to worry about fire again.
