Muscle building?

[GavinColeD]

I wanna start "working out" but not by going to a gym and stuff is there an easy way I could just do different kinds of excerises right from home like sit up or push ups to build arm muscles and abs?

If you go the gym would be better. It all depends of your expectations and body goal. I give you some examples and training:

Russian Twists, Leg raises, Crunches, Heel touches, Modified V-sites, Hundreds
(Level 1 "3 sets/20 reps") (Level 2 "5 sets/30 reps") (Level 3 "7 sets/40 reps") (20 minutes rest in between of each set)

Knee crunches, Cross crunches, Leg raises, Bicycle crunches, Flutter kicks, Heel touches, Elbow Plank, Sitting twists.
Reps in order: 10 , 10, 12, 20, 20, 10, 60 seconds, 10,
Levels: (Level 1 "3 sets") (Level 2 "5 sets") (Level 3 "7 sets")

Also: Military basics: Push ups, sit ups and pull ups. As hard as and as long as your energy and body takes it.

You can get a great set of abs, thats it.

For everything else, progressive overload is a must, and that can only be done with weigths

Abs are something you don't need a gym for. It's better to have a gym for the rest of your muscle groups though.

Planks are the best tried and true ab exercise as they work the entirety of your core. I also like leg raises or my personal favorite bottom ups as they work your lower abs the best as lower abs are generally the toughest to develop for people.

Depends on your body type. If you're skinny af, then you first need to gain weight and add fat to your stomach to transform that to muscle. Or if you have a little belly try to cut the carbs and workout

Well yeah, push ups, planks and different variations. Diet has more to do with strength and physique than working out.
But that being said, free weights really help a lot.
