填空题 Welcome to your first {{U}} {{U}} 1 {{/U}} {{/U}}training class. There are 15 different activities in {{U}} {{U}} 2 {{/U}} {{/U}}. Some make use of {{U}} {{U}} 3 {{/U}} {{/U}}and others don't. The idea is that you go {{U}} {{U}} 4 {{/U}} {{/U}}each of the activities. Ten of each first time, 15 second time and 20 third time. And in between each {{U}} {{U}} 5 {{/U}} {{/U}}you'll all come together in the middle to do some exercises.
Now before you start, we just have to {{U}} {{U}} 6 {{/U}} {{/U}}that you really think you're fit enough to do all this. Of course, exercise is good for you but it can actually {{U}} {{U}} 7 {{/U}} {{/U}}you. So what you've got to {{U}} {{U}} 8 {{/U}} {{/U}}for is if you've ever had any heart {{U}} {{U}} 9 {{/U}} {{/U}}, or any {{U}} {{U}} 10 {{/U}} {{/U}}in your heart or {{U}} {{U}} 11 {{/U}} {{/U}}. I want to know if you've often felt {{U}} {{U}} 12 {{/U}} {{/U}}or dizzy or you've been told that you had high blood {{U}} {{U}} 13 {{/U}} {{/U}}. And watch it if you've ever had an {{U}} {{U}} 14 {{/U}} {{/U}}, broken bones or any kind of {{U}} {{U}} 15 {{/U}} {{/U}}problem. If you have, come and have a {{U}} {{U}} 16 {{/U}} {{/U}}with me. Is anyone here over sixty-five? And last of all I just need to ask you if you've been doing any {{U}} {{U}} 17 {{/U}} {{/U}}exercise recently? So two or three times a week for two months or more? Even {{U}} {{U}} 18 {{/U}} {{/U}}to college or work every day at a good {{U}} {{U}} 19 {{/U}} {{/U}}? Right, that means we need to take it slowly at the beginning and build up {{U}} {{U}} 20 {{/U}} {{/U}}. So you're all fit and healthy? Good, let's get started.
