If you check, you will find it is incredibly rare for health and fitness books and articles to define "health", "fitness" or "exercise". Body by Science[0][1] gets right to it on pages 2 and 3 to define all three:

Health: A physiological state in which there is an absence of disease or pathology and that maintains the necessary biologic balance between the catabolic and anabolic states.

Fitness: The bodily state of being physiologically capable of handling challenges that exist above a resting threshold of activity.

Exercise: A specific activity that stimulates a positive physiological adaptation that serves to enhance fitness and health and does not undermine the latter in the process of enhancing the former.

It looks like the X3bar (really bands) suffer from the classic problem of mismatch to your strength curve, with the strongest resistance where your lifting is weakest. Nautilus equipment generally solved that problem by the 1980s.

Summary of research and evidence-based exercise as of 2009: Body by Science https://www.amazon.com/Body-Science-Research-Strength-Traini...

Author Doug McGuff MD has been operating a training facility since 1998, 100-120 client sessions a week, and he reports zero injuries to date. Most injuries come from excess force/acceleration, so pick an exercise protocol with very low acceleration that seriously fatigues the target muscle.

I got my exercise list from [1]. Per training I typically do 3-4 different exercises with one or two sets. I do not do any warm ups or stretching. I train mostly with machines as that is safer for me. Training purely with barbell inevitably triggers back pain.

While some are able to extract valuable benefit from gyms the vast majority are wasting time and money. In addition to that, most of these articles are very thin on reproducible facts and true research-based data.

This is, by far, the most interesting and useful resource I have found when it comes to fitness:

http://www.amazon.com/Body-Science-Research-Program-Results/...

The author covers cellular biology and debunks ideas such as "cardio workouts", treadmill bunnies, jogging and walking around your neighborhood to loose weight with plain-old science. Here you'll learn about the cellular metabolic process, Krebs cycle, Insulin resistance, fatty acid synthesis, glycolitic cycle, Cori cycle, Bohr effect, glycogenolysis, amplification cascade and whole host of other topics that are important, relevant and reasonably well understood.

What's more important is that everything that is proposed in this book is backed by science and scientific studies. It's like open-source software. If you care to dive deeper into why something works the way it does the scientific references are provided. The book has over 25 pages of listed references (about 10% of the book is reference data).

Anyhow, one of the claims of the book is "12 minutes a week" every seven to ten days. In other words, that's the actual time under load you need every seven to ten days to affect significant changes in your body. This does not include time walking around, watching TV or resting. Time under load.

I have to say that it works pretty much exactly as advertised. After reading the book I tried it and had a friend try it. We'd spend about fifteen minutes under load at the gym once a week. For me it changed to fifteen minutes every 9 to 12 days (you track your data in order to determine frequency). I got stronger with every passing week. Something that I was not able to do without a ton more effort in the past.

If you are interested in learning about this, start with Dr McGuff's (the author) videos:

Sounds like Chronic Fatique Syndrome to me.

My advice: cut simple carbohydrates out of your diet completely (veggies and animal protein only) and start exercising as much as your fatigue allows you. Read this book too: http://www.amazon.com/Body-Science-Research-Program-Results/...
