Swimming. I love it, but lately I have been very lazy about it.
Eat healthy consistently. Much simpler to just microwave a frozen meal. Ugh. For a while I was eating a lot of salads and it actually was easier, less clean up, but the raw veggies tear me up so badly I just can’t do it daily.
Spend an hour every day cleaning.
I don’t understand taking a cold shower, but if you love it I have a suggestion. Get into a warm shower and just end it in a cold note. It will be less shocking to your system. I don’t think the initial shock of cold water is good for you. I don’t have medical evidence to support that, I just feel that way.
