Do you guys know how to warm up before exercising? Did you know that stretching a cold muscle is an awful, horrible idea? Muscles perform so much better once they’re warm, and they only get warm by working!
Try some dynamic stretching. These ones are kind of low intensity without movement but you could try some of them while walking back and forth across a short distance.
My favorite isn’t on here but it’s THE FRANKENSTEIN, you walk with your hands out in front of you Mummy-style and as you walk you try to kick your hands. I do my hands at eye/forehead level. Hand walks are also a really great way to get the blood flowing.
