On Tuesday and Thursday's for one hour in the morning I participate in a Strenthening and Kickboxing class. Recently I have noticed that when I go from the floor to standing up I get dizzy. Do you know what would cause this? I have been doing this type of exercize for about 6 months so it really isn't new. Someone told me that it may mean that I am low in electrolytes but I have no idea. I drink at least 64 oz of water each day and the days I work out I drink double that.
