Learn the overarm pass: grip, arm action and body rotation of handball's standard pass, with partner drills and a shoulder-protection routine for the warm-up.
The overarm pass is a one-handed pass with the arm above shoulder height, so the same movement as the throw, only controlled instead of maximal. It is handball's standard pass because it covers distance without keeping the ball low. If you master it cleanly, you already have half the throwing technique in your arm.
The honest answer to "How long does it take?": most people have the basic form after a few sessions, while precision under pressure takes much longer. There is no reliable figure; this is experience.
Why the technique matters: in the throw, energy travels from the bottom up. A review of 14 studies found a fixed order: first the pelvis rotates, then the trunk, then the trunk flexes forward, followed by elbow extension and internal rotation of the shoulder, which reaches its peak speed only after release [1]. For you that means: the arm is the last link in a chain, not the engine. These data come from throwing; the same basic pattern applies to passing, only with less force. That is a plausible transfer, not a measured statement.
The more you throw from the body, the less the shoulder has to carry alone.
Hold the ball with spread fingers and the thumb on the opposite side, not in the palm. Wind up by bringing the elbow to about shoulder height and taking the ball behind your head (practice standard, not a study value). Milestone: You can show the position in the mirror without the elbow dropping below the shoulder.
If you throw with your right hand, put the left leg forward, toes pointing at the target. The chest first faces sideways and only turns open during the throw. This is where the chain described above starts [1]. Milestone: On a phone video you see a rotation of pelvis and trunk, not just an arm swing.
The elbow leads, the hand follows. Wagner and colleagues found in players of all levels that elbow flexion comes before internal shoulder rotation; with more experience ball speed increased and trunk flexion started later [2]. Translated: do not tip the upper body forward from the start, only when the arm is on its way. Milestone: The ball flies flat and straight, not high and limp.
Pass the overarm pass to each other, alternating with a bounce pass [5]. Aim at your partner's chest. Milestone: 10 passes in a row that arrive without your partner having to move.
Increase the distance step by step and combine with catching and the three-step rule. After the catch you have at most 3 seconds and 3 steps [6]. Milestone: Catch, step, pass in flow, 8 out of 10 on target.
In handball the throwing arm carries a lot of load. In a study of 660 players from the Norwegian elite (45 teams), a shoulder programme run three times a week in the warm-up lowered the risk of shoulder problems by 28 % (OR 0.72); for substantial problems the difference was not clear [3]. A meta-analysis across several prevention programmes in handball found about 40 % lower odds of shoulder injury (OR 0.60) [4]. If you pass and throw regularly, you should build such a programme into your warm-up.
If shoulder pain persists after training: rest and have it checked. This guide explains and motivates; it does not replace supervised training or a coach.
Pass in the rhythm of the throw. Run the whole sequence catch, step, pass in the same rhythm every time. That has two advantages: you develop a feel for the three-step rhythm that matters later in the standing throw, and you can dose speed and force without changing the technique. A partner who calls out the distance at random turns it into a game.
You hold the ball behind your head, put the opposite leg forward, turn pelvis and trunk open and let the elbow lead. The hand snaps the ball forward. In throwing studies the movement runs from the pelvis through the trunk to the arm [1].
For beginners 4 to 5 metres has proved its worth, as also suggested by the Swiss Federal Office of Sport for partner passing [5]. Increase the distance only when 10 passes in a row arrive without your partner moving.
Often the rotation from the body is missing or the elbow drops, so the shoulder works alone. A shoulder programme in the warm-up lowered the risk of shoulder problems in elite players [3]. If the pain persists, have it checked by a doctor.
After catching you may take at most 3 steps and hold the ball for at most 3 seconds before you play it. If you dribble, you may take 3 steps again afterwards [6]. So passing from a run is allowed as long as you respect the step rule.
