Yes for me too.
I had a period of not sleeping well that I put down to red lining the intensity side of things with sprinting. It doesn't take much speed volume to overdo things - at least for me. Off sprints now and doing Q&D and sleeping well.
As with all things stress related there are so many nuanced variables but if I were to generalise, again for me, it is linked (from an exercise viewpoint only) to neural excitement. I wouldn't say overtraining per se but certainly the frequency of intensity matters.
Q&D, like S&S, is low on neural input. And, by design, low stress, metabolically and physiologically, the movement patterns being less complex. So there is just the right amount of stress allowing good recovery - and sleep.
Also, I don't eat so much. I'm lean, sprinting is so demanding of energy that I eat all the time in training and post competition. At the moment rarely am I hungry. I don't count calories and use my eyeballs so no idea of numbers but about halved according to eyes and belly monitors.
So all in all, excellent. Get me some sleep, get a bit leaner and stronger before red lining it again. Ooops.
I'm using Sit Through's [5/5] in place of push ups on occasion. I referred to this as, "Workout In A Small Space". If you are a grappler, this works out well. It's a nice combination. I've done an article on that based on my experiments. I won't link to it since I want to be respectful of the community here. However it's not hard to figure out.
I have a Whoop device which measures my day strain and recovery. Since doing Q&D 3 times a week my recovery's are way higher. I even had a 5, then 1 one yellow day, and 9 day streak in the green! (recovery higher than 70%).
