anyone notice water retention after cardio of hard training

[dan999]

i have started to not a lot of water retention under the skin after doing cardio and weight training. i also noted this a few days back i went on a very long walk few hour but the time i got back home i water logged under the skin. was reading about cortisol being elevated after training. i then had a day off then noted the water dropped a fair bit, anyone had this or know much about cortisol or had a issue with it in the past
