I like swimmimg and I am fine in the water for half an hour - I don't overdo it gentle swim and just moving those muscles. I feel great when I get out and have a good energy level.
I usually swim in the morning - but my issue is that I become incredibly tired around 5pm and then I sometimes sleep on the settee for over 3 hours and still sleep OK at night.
I dont want to get exhausted however I must say it is good to feel so relaxed.
I know it is important to pace myself and to exercise but I am not sure if I am doing too much.
