Any form of exercise will make you feel more alive. Nature did design us to go running after animals in the forest and try and kill them, which would have been hard work. :lol:
Swimming, can't beat it. I used to swim all the time years ago and like most people gave it up for things like pubs. I took it up again in April this year to get myself moving again after that accident I had back in Feb'. Its been working a treat along with some Osteopath treatment.
My local pool is 33.3m, an old one from the 60's and its a bit bigger than the standard public pools. It took me an hour to swim 12 lengths when i first went and now I do around 40 in the same time and it definitely makes you feel more energised and fit. Plus I've lost a stone so it can't be bad.
