There is no need to over-complicate things where exercise and fitness is concerned (quite the reverse, in fact). I also tend to find that when workout programmes become very technical the people who are expected to do them begin to lose their momentum not long after starting them. Why? Because without an engaging and understandable regime, fitness can become difficult to maintain.
Beware the experts (apart from individuals like myself, obviously).
Instead, try to structure your fitness programme around tried and tested building blocks that can be learned and remembered without reference to a diagram. Plus, look for such building blocks that you will remember how to undertake in a couple of days time.
If you cannot remember what you should be doing at your next workout because there is too much detail to recall, you are unlikely to maintain the programme.
Make your exercise programme a welcome part of your life. Adapt it to your circumstances and deliver each part of it with the appropriate level of attention to detail. That way, lifelong fitness lies.
And on that note, I leave you with this video which, I hope, demonstrates the points I am making above.
