Have you had trouble finding a good way to exercise? Why 1 (et ryhdy =(ota)) up swimming in that case? It 2 fat as fast and as much as for example running. However, the water 3 (kannattelee) you when you 4 (uit) and so there 5 ((ei) ole) hardly any pressure on your joints. And what is better, it 6 (on) an effect on more muscle groups than eg cycling. So if you 7 (satut olemaan) over-weight or 8 (on) an injury or maybe even asthma, there better way to exercise than swimming. You 10 (pysyt) in shape and have fun at the same time. Yet you 11 (et voi oppia) swimming from books. You 12 (täytyy tehdä) it yourself in the water. If you 13 (haluat tulla) a professional or if you 14 (aiot) compete in swimming, you'll have to find an instructor to guide in the technique. The technique a swimmer 15 (käyttää) may make his and back hurt if he 16 (ei tee) it right. When you 17 (harjoittelet), remember to breathe right too. Your swimming 18 (tulee) much more efficient that way. If you 19 (työskentelet) hard and 20 (et tuhlaa) your time by taking it too easy, you'll soon be swimming a mile in 30 minutes.
