I was walking around our complex r cently and discovered a pile of free stuff done neighbors dumped near the mailboxes. They were either doing a major declutter or preparing for a move. I picked up a huge round tub made of sturdy red plastic.

Now I fill it with water almost to the brim and keep it in the bath tub. In the morning, I step I to the tub and stand there, counting to 100. It is not as good as a full cold plunge, but it is good enough - it causes a release of endorphins and gives me energy to face the day.

If you are interested in trying this method, I will check on the bottom of the tub for its make and model.
