1 00:00:02,730 --> 00:00:07,070 ‫Industrial we're going to swim between three to five times 50. 2 00:00:07,290 --> 00:00:13,560 ‫Rest 15 to 20 seconds between each 50 first lap is going to be fast. 3 00:00:13,560 --> 00:00:15,890 ‫Second lap is going to be slow. 4 00:00:15,930 --> 00:00:19,680 ‫First lap you count your strokes in the second lap. 5 00:00:19,680 --> 00:00:25,450 ‫You have to swim two strokes exactly less than the first lap. 6 00:00:25,560 --> 00:00:32,410 ‫Let's say for example the first lap was twenty two strokes the second lap has to be 20. 7 00:00:32,430 --> 00:00:39,120 ‫So you need to swim fast in the first lap but not too fast because then the body's going to get more 8 00:00:39,240 --> 00:00:40,050 ‫oxidized. 9 00:00:40,050 --> 00:00:47,070 ‫The goal in this exercise is to learn how to glide in a long gait the muscles after swimming fast.
