For me... warming up my body before I do any kind of weightlifting is very important because I don't want to pull or tear any muscles. Prior to this, I used to do a light yoga stretch when I first arrived at the gym. That proved not to be enough warm up for my body because I actually pulled a muscle in my upper shoulder that still hasn't healed. Now, I do what I call a Cardio Warm-up that actually targets every muscle in my body. At the same time, I warm up my abs by lying on a mat and working them in-between my step-ups, I included this in the video also. I give you a really short 3min video demo but my entire warm-up routine is about 30 minutes. I do this every time I arrive at the gym for now.
