Bro, I'm doing the same workout at the moment... nice and simple. I had a week off last week and just got back into it this week. It's crazy, after a week off and getting back to training, my muscles are actually sore. Sounds odd but I miss that feeling. It's interesting why that happens. Now I'm questioning if I'm not pushing myself enough to get sore all the time lol?
MMA is also a great way to do cardio. I was doing that with Jujitsu but recently put my membership on hold for 6 months. Just haven't had the time to fit it all in. Hopefully I'll get back into it again.
Nice hearing from you brother!
