That morning she had been practising a special kicking movement and her upper thighs ached from the exercise.

His thighs ached as his feet pushed him up the rise on the other side.

Her thighs ached from the effort, but she pushed harder, her feet pounding.

After a couple of minutes it wasn't funny: His thighs ached.

Her hips and thighs ached and were stiff, but revealed no serious hurt.

His thighs ached and he realized that he had half-risen.

Then he turned and walked slowly toward the meal hall, conscious that his thighs still ached.

My inner thigh ached again after the long walk over.

His thighs and shoulders ached, so maybe it was just a virus coming on.

He stood slowly; his thighs ached from hours of sitting cross-legged.
