I stand by my advice.
No fancy equipment - you need a floor, some push up handles and a bar for pull-ups. Get some variation and technique tips from YouTube; you'll be able to tell who know what they are talking about, I hope!
I guess I didn't stress rest enough (it's critical) and it does make sense to start slowly if you have been doing -zero- strength training. But, IMO, doing reps until you can't do another is a generally accepted method to build muscle.
Perhaps diet hasn't been stressed enough. I follow the 1 gram of protein for every pound of body weight, or close to it, theory. I use 100% Whey which only uses stevia as a sweetener. I have evolved over years into a diet that I could not have done in a short period of time. No sweets, sodas and almost no bread products or processed food. Lot's of yams and other "good" carbs, fish oil, flax, borage and pumpkin oils and lean proteins. I think the diet side of it is more important than the physical activity part of it, but obviously both are important.
I also don't see where carnutzz turned everything said before on its head??? There's more than one "right" way to go and many folks have their own philosophies when it comes to diet and muscle building. Your physiology should have a lot to do with your program - good advice above about spending some time with a trainer and nutritionist and even doctor as well.
I know what works for me, but that may not work most effectively for you.
Best,
