Streching before lifting is counter productive and could cause injury if you are NOT warm. Cold stretching can lead to hurt/torn muscles. Warm up and then stretch.
He's curious about running, not lifting
Warm up a little first, enough to get a light sweat.
Stretch calves, quads, groin, gluts, hip abductors, sides/ribs, abs, and shoulders.
You should have recovered enough from your warm up to be good to go by now.
