WEBVTT 00:00:01.000 --> 00:00:05.000 OK, now this next exercise is good for your upper back. 00:00:05.000 --> 00:00:07.000 Lie on your back. 00:00:11.000 --> 00:00:18.000 OK, now, you have to bend your knees up, but keep your feet flat on the floor. 00:00:18.000 --> 00:00:23.000 Now, bring your knees up towards your chest. 00:00:23.000 --> 00:00:34.000 That's right. Now, grab your knees. And very gently pull them as close to your chest as you can - don't force them. 00:00:34.000 --> 00:00:35.000 That's easy. 00:00:35.000 --> 00:00:40.000 That's not all. Now you have to raise your head and shoulders towards your knees. 00:00:43.000 --> 00:00:44.000 Oof. 00:00:44.000 --> 00:00:46.000 Do you feel a little tension? 00:00:46.000 --> 00:00:47.000 Uh-huh. 00:00:47.000 --> 00:00:53.000 OK. Hold it for five more seconds - three ... four ... five. 00:00:53.000 --> 00:00:59.000 OK, now don't let go yet. Pull a little further and hold for another 10 seconds. 00:01:00.000 --> 00:01:02.000 I can't. 00:01:02.000 --> 00:01:05.000 OK, relax. Take a breath. 00:01:05.000 --> 00:01:07.000 Now try again.
