This screen selects a conservative practice lane. It cannot diagnose a condition, determine medical safety, or clear you for breath-holding. When uncertain, choose no-hold practice and speak with a clinician.
Stop any session that causes dizziness, visual changes, faintness, chest pain, palpitations, wheezing, confusion, panic, or loss of coordination. Never hyperventilate before a hold and never practise holds in water, while driving, standing, walking, or using machinery. Keep prescribed medication, inhalers, CPAP, and other treatment unchanged unless your clinician directs otherwise. © 2026 Ken Hoyer / Body Plus Fitness.
