Okay, now this next exercise stretches your thigh muscles, but with the overall effect of strengthening the muscles in your lower back.
Which is where I'm weak.
Exactly.
By tightening up your thigh muscles, we can take some of the strain off your back.
Okay, so now take hold of the back of the chair and bend back your leg.
Now grab your ankle and gently pull your foot so as to touch your buttock.
Okay, now stretch your thigh backwards at the same time, like this.
But keep your back straight.
Just breathe normally.
That hurts.
Where?
My knee.
That's because your back's not straight.
Straighten up.
Do you feel it now, in your thigh?
Yeah.
Okay, you should hold that for 30 seconds, breathing normally.
Try it with the other leg.
Okay.
