Not everyone has a full gym in their living room and many people may not have enough disposable income to go to a gym every day. So, you have to keep the exercises simple, requiring as little gear as possible.
I wanted to post something like this partly because of some of what you said in your post. I like where you were coming from with your workouts to strengthen lower back and under-developed parts of legs, but some of what you said, and I do not want to step on anyones toes, was wrong.
The back is comprised of some of the largest muscles in the body, and by no means does working them out cause back pain / injuries, unless you practice careless form when training. It is very important for people to do exercises to strengthen their backs when they are young, and continue to do so as they age to alleviate/remedy complications often experienced later in life.
When I say it is important for people to do exercises to strengthen their muscles, I do not mean you should be trying to deadlift and squat 2x your body weight or anything like that because that does not fit everyone's goals. Simple exercises like back extensions as you mentioned are very simple, easy, and effective.

Everyone's goals with weight training are different, but generally it can be divided into endurance / hypertrophy / strength routines.
The most effective routine for beginners however would be something that preaches frequency>volume in workouts, so full body routines would be a very good start for most. With these workouts, you focus on compound lifts, like squat, deadlift, bench, over-head press, bent over rows, etc. These lifts target more than one muscle group, and the workouts can be performed in a short amount of time (30-60 minutes).
For those who cannot afford a gym membership, or an at home gym, it's obvious not all of this would be possible for you. There is only so much you can do from home without the proper equipment, but body weight squats, push ups, pull ups, core exercises etc. are better than doing nothing at all.
