While the rower in the third picture does raise good points, I feel like there are couple of points I would add.
>Alternate between strenght training and aerobics, if you do both in quick succession, any gains you might have gotten will likely be negated by the other due to different types of stress these exercises will put your body through
>Don't cheap out on the running shoes, do your research and buy accordingly. Different tools for different environments
>Rest. Rest is as important as the exercise itself
>Listen to your body, always keep in mind that stress-hormones released into your bloodstream during exercise WILL affect your perception of pain, if your legs or knees or whateverthefuck starts hurting fucking stop. Cutting exercise short is far preferrable to not being able to exercise for weeks or months because you outright broke something
>Get a kettlebell, that's probably one of the most cost efficient exercise tools you can get
The only reason I am capable of functioning after losing my dog is that I end up making promises to other people. I have no family left after my dog died bit over month ago. Yes, as stupid as it sounds, a dog was the closest thing I had for a family in my life. I've got no one I can talk about personal problems, or even really talk with, other than anons on various chans. Frankly speaking the only reason I even put food in my mouth nowadays is to sustain my body so that I can atleast keep promises I have made.
I suppose once I have fullfilled all the promises I have made, I will start fasting and meditating until I come to solution. Either I will find some solution to this issue or I will not. Either outcome will be acceptable.
Barbara Oakley's "Mind for numbers" will be useful. Read it and learn to study more efficiently.
As to exercise routines, much the same rules apply. There is no point in overdoing it, exercise should be something you do for fun. Essentially you need to sort of educate your brain with a positive feedback loop.
