Keeping your muscles warm before starting exercise is really important, which is why all fitness instructors emphasize a warm-up. I like to go a little further by wearing clothing that keeps my body and joints warm before I teach a class. I'm really glad I chose this zip-up hoodie from LOFT’s Lou & Grey line. It’s so soft and kept me at just the right temperature before I was ready to start teaching. It kept the chill of the day out and the warmth in without being too hot. I usually layer up underneath, and although I bought a size small, an extra small might have been perfect for a snuggler fit. LTKfitnessgoals LTKootd LTKActive
