Water Retention and Aerobic Exercise

[triathloncoach]

Is there a strong correlation between sweating during aerobic exercise and a reduction in water retention? If I increase my cardio intensity and/or volume will I see a drop in water retention? I know I sweated out many pounds to make weight as a college wrestler - is this the same as reducing bloating?

Water retention with Dec/test/gh. I'd rather not go the diuretic route. Of course my diet needs lots of work. Is sodium the big evil or is it junk carbs?

Suggestions please
