Release angle too low
Most common. Release angle below 35 degrees produces a low, dying trajectory. Drill: standing throws with a target marker at 35-37 degrees; calibrate the body angle to the release angle.
A low-flying discus dies short, no matter how strong the release. Optimal discus release angle is 35-37 degrees; most under-throwers release at 25-30. Below: the three causes of low trajectory, and how to fix them without losing release velocity.

Wrist breaks below neutral at release, pushing the discus downward. The fix is a firmer wrist through release. Drill: slow-motion releases with a partner watching.
Throwing maximally without rhythm forces the body to muscle the discus, often at a lower angle. Slow the run-up, find rhythm, release angle rises naturally.
Discus trajectory is the most diagnostic single number in the event. Film a throw side-on, AI measures release angle and wrist position. Most under-throwers don't realize their angle is 8-10 degrees low.
