Very good points Hlezama! Working out togethergives us great motivation!
And walking to and from work is a great way to stay in shape! I used to walk all over Bogotá because my teaching job didn't pay enough to actually take a bus between students!
There are all sorts of activities to do, even isometric activities that can be done by prisoners! I hope to try out new exercises soon :)
Be blessed, el mundo ya se esta cambiando!
