All my life been occupied with some activity, but now I am doing strenght training 6 days a week in a 3 split for the last 8 years with a few longer brakes because of work, and low intensity exercises, walking, hiking, swimming, rowing, padling just depending on where I am, and whats available.
Water regime is manageable if you always drink 300cl every half an hour from 6 in the morning to 8 in the evening.
And when exercising I always drink more, especially here in Thailand.
First thing when I wake up before coffe is 300cl, which sometimes is 5 already.
