Hi Cathe! Just wondering how my a.m. coffees affect workouts. I'm a teacher off on summer break and I've been able to enjoy a cup or two of coffee before my a.m. exercise lately. During the schoolyear, I don't have time and roll out of bed at 4:35 and go straight into your warm-ups! I do feel more energetic after some coffee, but I notice that I cramp more and definitely worry more about incontinence! x( but I wondered if there is any research on positives/negatives regarding caffeine and workouts. By the way, my tapes should be arriving any minute! Can't wait!
