From the article, I do appreciate the bit about super slow weight lifting. I have done this before with successful results, and I actually forgot about this technique. It's a good way to shock the muscles into growth. However, again, it's about variety. My body can burn out from doing too much super slow weight lifting, just like doing too much of anything else.

I fit in traditional cardio (e.g., jogging) whenever I can. For strength, I don't have time for the gym. So, I do a modified version of Grease-The-Groove (GTG). I recommend this option for people with tight schedules who work at home or at a place where GTG is possible. My strength is just as good, or better, than my strength when I was going to the gym regularly.
