I started at home since last december, AND loving it.
At the begining i was like, i CAN'T live without the leg press, or the leg extension machine ... most of the contras i saw was from me getting a proper legs training.
But i got on the bodybuilding website, and they have TONS of exersices you can do at home. This is the picture of my home gym, it does not have all the thing i want, but i have dumbells, bech, bikes for cardio, weights and a bar, i can do a lot of compound movements.
I do have more weights now, does pictures are from december, the first things i bought.
And i think having the gym at home is easier, cause you'll make your workout at the moment you can, not have to go to the gym, sometime is crowded ... ufff. Sometimes, when i have a very busy day, i do my workouts pretty late at night or pretty early. The only thing i suggest is don't buy too much stuff cause not everyone like to train at home (i was one of those, but most because i didn't know what to do, and i felt totally limited) now i love to train it at home.
You don't need all the fancy equipements we can find in the gym, actually compounds exercises and working with dumbells is much better.
