Of course the level of specific exercise anyone requires depends on what the usual daily activities are. In my particular case I'm retired, so there could be a temptation to watch the share market from go to whoa. I usually go for a 45 minute bike ride (these days not too vigorously) during the trading session, and have a walk or swim in the afternoon after the market closes.
I absolutely agree that everyone needs a physical break from their day job - I miss my jungle walks (when I was a practising geo)!
Exercising the Forums! Remember the "physical exercise" too.
I think we can get stuck in the chair here reading things of sharemarkets.
So thinking we should exercise physically to maintain the physic too.
Go for a walk, cycling ect.
and I have found the app: 7 minute workout is good.
Good preparation is part of the strategy.
Any other suggestions out there?
