Quick Stretching and Exercsing for Lazy People?

I'm a fat and lazy ADHD Taurus, kind why I'm here on MFP! Looking for quick, 5minutes or so, stretches and light strengthening exercises I can squeeze into my rushed schedule.

I've got about 5 pounds to meet my goal weight
I am a single mom to three special needs kids. I don't have much extra time, motivation, or brain energy (this one is really key.) I figure if I can sneak in a few minutes here and there I will be motivated to push for a few more at a time.
I have five pound hand weights and a yoga mat.
Important to note that I have a pretty bad pelvic prolapse, which restricts me from doing some of the more intense core strengthening exercises. I discussed this in another thread and got a link to some ideas I might be able to do safely.
My overall goal is to get my pelvic prolapse exercises worked into my hectic day, a goal of 90reps of a variety of exercises total per day. Theory is that if I do 30 at a time in 3 sections during my day, which takes under 5min, and add in some general stretching and light exercises I will feel physically and mentally better all around. I might be motivated to push myself further after mastering this. Motivation and change of routine, or even mastering a new thing, is challenging for me. Baby steps?

I have tried yoga a few times, from YouTube videos. I absolutely detested the experience. I hope to one day have access to an actual yoga instructor, perhaps that would make the difference, but right now just doing yoga isn't my thing.

Suggestions please?
