Trainer note summary: 30-minute sessions are enough to grow arms if Amit keeps progressing. 45–60 minute sessions could allow more work, but more work is only useful if recovery and joints tolerate it. Since elbows are already giving mild warnings, do not blindly add more volume now. Keep sessions focused, repeatable, and progressive. Current decision: keep sessions around 30 minutes. Reassess after 4–6 consistent weeks. If arm measurements, reps, or visual progress are not moving, add volume carefully — probably 5–10 minutes to the arm-specialization day, not longer workouts across the board.
