Re: Fitness freak
It's up to everyone themselves, ideally in consultation with their doctor, to decide what the right exercise routine is or if it may be too much. It would depend on the state of their health and their personal fitness. And one should feel good after each training. You don't say how old you are and whether you did any sport before retiring. Nor do we know how intensive the weight training is. So, it's impossible for the reader to answer your final question.
Our gyms have been closed since November. Before that I went to the gym 2-3 times a week as a retiree and once a week while I was still working. I usually warm up on the treadmill for 10 minutes and then use the machines for about an hour, which I now do at home as far as possible due to Corona. Then I used to finish off on the treadmill again with a 20 minute run. In addition, I run outside, formerly once a week and now 2-3 times a week.
I'd venture to say that my workout is definitely not too much. Firstly, because I have exercised regularly as clockwork apart from playing tennis since I was 15. Secondly and most importantly, my ambition has always been directed at just this regularity and not at measuring reps and sweat. It has done me good.
