All strength had seeped out of my body as it might have drained from an open and deadly wound.

His strength was seeping from him rapidly, the wind increasing in force.

His strength was seeping from the bullet wound in his shoulder.

He was walking slowly now, his strength seeping out of him along with the blood running down his side.

Sweat began to dry and strength seeped back into my limbs.

The strength was seeping out of my muscles.
