When I use the TRX on my own, I'm not that organized. But I feel like the 15-30 minutes I spend is worthwhile. I stick with the exercises I'm more familiar with so that I know what good form feels like. Mostly I've done that when I'm away from home.
If you want to feel/be more organized try to incorporate all 5 basic movement patterns into your self guided workouts:
Bend and lift movements -eg: squatting
Single leg Movements -eg: lunging
Pushing movements - 4 directions - forward, overhead ( harder to incorporate on TRX, there is a pike push up but best for higher levels - which you may be), lateral, and downward.
Pulling Movements - rows etc
Rotational - single arm rows with rotation would combine this movement with above if you need to save time for example.
Core workout should incorporate 2 of each of the following for athletic training but at least 1 is sufficient for overall fitness:
stability - all trx incorporate this so no need to think about this one except maybe some sidework.
rotation- single arm row with rotation would be one.
extension-I had a hard time finding any on the TRX but will let you know if I do, or maybe you know some you could share with me.
flexion- There is a prone roll out which I am sure you probably do.
Keep in mind the beauty of full body/functional exercise is that many single exercises incorporate 2 or more of the above in a single exercise so it is possible to fit all in a short work-out.
