I hear that, and fun music is how I enjoy it. I listen to a lot of reggaeton and cumbia. Knowing that I’m getting stronger, and improving my future living standard, are also plenty motivating. Like I said, back pain and then no back pain? I’ll do it.
It also scared the shit out of me to realize that some people my age couldn’t do an air squat… I don’t want to get old like that!
But, movement and strengthening in general is where it’s at. This works for me, but whatever keeps you interested. I don’t mean to make this an ad for my exercise routine!
