I do NROL4W at home. I use:

A Swiss Ball $17 at walmart
Weights $89 at walmart
Foot stool $10 at walmart

I use youtube to explain the exercises and to find alternatives at home by using the exercise I want the word dumbbell. I really enjoy it!

^^^ i do exactly what she does. now nearly done with stage 1.
I'm thinking of getting a normal barbell for stage 2.
But it IS doable at home, just abit modified (especially deadlifts and squats).

I'm just restarting NROLFW at home (I did most of phase 1 and quit last year). We have quite a bit of equipment at home, but I tend to stick to the dumbells although we do have a barbell. The only issue with it is that I know I could squat a lot more if I could do it properly with a barbell on my shoulders rather than holding dumbells. But other than that I haven't had any issues with doing the work outs at home.
