Simplicity Is Best

I've read thousands of articles on training, and probably put together thousands of training plans. Most of the plans were only used a few times, if at all. I learned from this.
What I learned was that most people are lazy. It doesn't matter if you work out a fancy 12 week double progression or conjugated periodisation. Most will simply stop using it after the novelty wears off, if at all.
So now my training advice comes in bite-size chunks. Fitness-tweets if you will.
Drink more water.
Eat fewer carbs.
Walk for 15min every day.
Do a push, a pull, a squat and a hinge every workout. And some core.
What about sets, reps, rest periods, % of max? I don't really care. If a person actually does follow through on the advice, they will improve. If they eat fewer carbs, or walk every day, they will get some results. If they like that and decide to ge more serious, then we can talk. If the don't then I've avoided spending my time and effort creating a plan for nothing.

If you decide that simple and sustainable is what you want, and you're willing to put in the work check out info from the coaches that know how.
Check out Mark Rippetoe, Jim Wendler, Dan John. They have plans that you can easily follow. Calculator, stopwatch and numerous exercise machines not required.
Oh, when I say 'easily' follow, it has to do with mental energy. Rest assured that you'll need a lot of physical energy...
