Day 1: Chest/Back + HIIT Cardio
Side note(s): Shoulders are my absolute most favorite body part to work. I could quite honestly train them and only them, but clearly that would be very unbalanced! Also, you will notice I only put in one bicep exercise (right at the end). This is because the bicep is (relatively speaking) a very small muscle group. And, with most moves you engage your biceps anyways. For me, I don't see a huge need to focus heavily on them. I just try to lift them as heavy as I can to exhaust them at the end. Adjust if you wish!
1 (a). Rope/Cable Overhead Extension
4 (b). Alternate DB Press
4 (c). DB Curl
Make note that HIIT Cardio does not always have to be running sprints. Running sprints is a phenomenal way to get your HIIT in, but for people like me with physical problems (plantar fasciitis in my case) I can't always run. But don't make that your excuse to "take it easy." It's still called HIIT. I made mine so hard today that I thought I was going to throw up at the end!
My entire workout lasted about an hour today. I was shaking and "spent" by the end. I went home, re-fueled and I feel fabulous now! This is how our workouts should be!
