Open up tight triceps with an easy overhead reach.
Keep it gentle and never bounce, just relax into the stretch and breathe.
Reaching overhead and dropping your hand behind your head takes the triceps, especially the long head that crosses the shoulder, to their fullest length, and the gentle press from the other hand deepens the stretch one arm at a time. Because pressing and overhead work leave this muscle short and tight, a slow hold here is one of the easiest wins for shoulder comfort. It belongs after push days and overhead sessions, or any time the back of your arms feels bunched up.
After training or between pressing sessions, when the muscle is warm and has just been worked. Long holds right before heavy pressing can slightly dull output, so save the deep stretching for afterwards.
20 to 30 seconds per arm, breathing slowly, repeated once or twice. The pull should read as a comfortable stretch down the back of the arm, never a pain in the shoulder. Ease off if the shoulder joint itself complains.
Almost everyone has a dominant side that does more daily work and holds more tension. Give the tight arm an extra hold and it usually evens out over weeks. A big difference that never changes is worth showing to a physio.
