I spend 30 minutes doing running, 30 minutes stretching doing core exercise like crunches and plank, and another 30 minutes for strength training. I do this all in the morning before my class. After my class, I swim for 2 hours in the evening. So overall, I spend 2 and half hours everyday except for Mondays because I don't swim on this day. The rest I always do. Three hours is a big deal and not easy to snatch on other things, but as much as I could, I manage to attend to this routine. Not easy though.
