I just went on a 20 minute bike ride. I haven't been riding a lot lately so I went slow and gave myself a 5 min. break. Now, I feel dizzy and like I'm goin' to throw up. Is this a normal side effect of exercising when you haven't done something as strenuous (sp?) as bike riding, is it from the heat or do I just need to eat? I walked 2 miles yesterday without a problem, why do I feel icky today? Any comment is welcome. Thanks!
