Similar for me, early 40ties, started June with strength training and been combining this with mat/reformer pilates and cardio on a bike trainer. I can also say its been life changing. I'm not boasting or anything here, but I went from a skinny guy to a what one would call a "ripped" guy in a matter of like 2 months. I was (and still am) completely astonished how a human body can change so fast.
