Cool exersise for various muscles

It makes you feel tired to look at it - but you actually do it more slowly so it is not as exhausting as it looks. I do a number of exercises like this which target all the muscle groups over two (relatively) short sessions. This week I have tried out some new ones as well. I try to make it to the gym now at the start of most days when I am not doing something else. Going to the gym  has added a great deal to my well-being. With the additional benefit that it makes depression (when it strikes) less painful. And no sweating it out on the machines either - .

This is the hardest but is done more slowly than the picture
