I dont know if this belongs to the training board. Today im so dizzy. i was on the threadmill for an hour. how can i prevent this?
well i started cardio 2 weeks ago, and mostly im on the bike and walking the threadmill. But this time i was running for 15 min first then walking 45 min. if i cant take that, what good is cardio anyway?
