Couldn't agree more. Loaded compound movements are just unreasonably effective. A nice added bonus (I find) is the therapeutic aspect of lifting. I think some of it is simply that it's almost a form of meditation in the sense that you block out all other thoughts and are focused on just on the movement and your own body.
Not to get too melodramatic about it, but squatting in particular teaches you mental toughness and is a great metaphor for life: you shoulder a burden and when you get down (the descent) you dig deep to come back up again.
I have a garage setup, so trying to work out 5-6 days a week by mixing it up. The rack, flat bench, Olympic barbell + ez bar, plates, rubber mats is truly everything I need - and all for less than a highest end phone. It will last my lifetime, and extend it as well. (I ride to work for cardio.)
And yes, the lifting feels like such a relief compared to dealing with family or work. It's amazing how much it can clear the mind.
You'll probably still feel it the next day nonetheless, when you can go again with a slight increment.
Keep this up and before you know it you're back to where you were.
Also this whole thread is great. Weightlifting is the best medicine bar none for this middle aged mostly desk bound programmer. It has immense mental health benefits as well.
