WEBVTT 00:00:01.000 --> 00:00:05.000 OK, now this next exercise stretches your thigh muscles, 00:00:05.000 --> 00:00:09.000 but with the overall effect of strengthening the muscles in your lower back. 00:00:09.000 --> 00:00:10.000 Which is where I'm weak. 00:00:10.000 --> 00:00:16.000 Exactly. By tightening up your thigh muscles, we can take some of the strain off your back. 00:00:17.000 --> 00:00:22.000 OK, so now take hold of the back of the chair, and bend back your leg. 00:00:22.000 --> 00:00:28.000 Now, grab your ankle, and gently pull your foot so as to touch your buttock. 00:00:28.000 --> 00:00:40.000 OK, now stretch your thigh backwards at the same time, like this. But keep your back straight. Just breathe normally. 00:00:40.000 --> 00:00:42.000 - That hurts. - Where? 00:00:42.000 --> 00:00:43.000 My knee. 00:00:43.000 --> 00:00:47.000 That's because your back's not straight. Straighten up. 00:00:47.000 --> 00:00:50.000 - Do you feel it now, in your thigh? - Yeah. 00:00:50.000 --> 00:00:57.000 OK. You should hold that for 30 seconds - breathing normally. Try it with the other leg. 00:00:57.000 --> 00:00:59.000 OK.
