Once per day, when peeing, do it differently. 1. Release the stream during the in-breath. 2. Stop and hold the stream on the outbreath. 3. If not yet bored or tired go back to 1. Else - finish peeing normally. That's it.
And note that for most people, a week to few weeks of the exercise give stronger orgasms and ability to delay the ejaculation.
I've experienced all those benefits when I started walking two times a day, 8-10 thousands of steps a day continuously for several weeks. I haven't performed any other exercises.
But it's really boring and you need to do it every day. I do it only because I need to walk a dog.
One such prescription would be to do deep work early in the day then walk after and walk again 2 hours before bed. Another would be split the deep work with a 1 hour walk and do the 2nd walk after the 2nd block.
It may be more fulfilling with lots of interesting ideas rattling around. YMMV
