Elbows are generally most effective when used in combination with punches or kicks to allow the fighter to close the distance.
Elbows are also used in mixed martial arts as part of the "ground-and-pound fighting tactic. Participants often use elbow strikes in conjunction with punches while in the "full guard, "half guard, "side mount, or "full mount in order to knock out or overwhelm the opponent.

These activities will also make the surrounding tissue harder to bruise due to buildup of scar tissue in the striking point of the elbow from elbow strikes. It is not recommended to strike solid objects for conditioning as "micro-fractures in bone or other tissue tend to be a risk factor for repetitive strains or even more acute problems.
