Figuring out what to do is a big part of the challenge for me too. I workout at home and follow video guided exercises using the Fiton App which is free for most content. I started with no weights, but have since gotten a few sets of dumbbells at different weights.
This is true for starting anything. When I'm getting ready to run, I know I have a five minute warmup then a stretch, then the run, but when I start, it's just a five minute warmup -- nice and easy, no rushing.
For a work example, if I'm dreading starting something, I'll spend a little time the day before just getting ready for it. Get the data accessible, write a checklist (as above, very helpful for offloading brain work onto the page), get reference documents ready (printed), etc.
Ty, I had the same question
