Traction exercises are strength exercises that involve a concentric contraction-the contraction of a muscle when two points of connection are moved closer together. Examples of deadlift exercises include bicep flexion, hamstring flexion, and downlift.

These exercises are the opposite of push - out exercises-eccentric contractions that involve lengthening the muscle and controlling resistance while removing the connection points. Examples of push-up exercises are chest presses or shoulder presses.
