It depends. If I’m stretching as I get out of bed to loosen up and get mobile, then no. Otherwise a light jog on the spot, a mini aerobic workout (3-5mins) or the hula hoop beforehand can be good to boost energy, blood flow and loosen the muscles before you stretch.
I was going to write ‘no’ at first but I do actually warm up. Stretching is one of the first things I do in the morning, and I have a bit of a walk around my house before I stretch. So I do warm up, but it’s becoming part of my routine, so I didn’t really think about it that much. It’s just what I do now.
