Although flexibility and strength training exercises are important components of your overall fitness program, it is aerobic and endurance training (cardio) that provide the greatest benefit for reducing blood pressure. Exercises involving heavy resistance and strain, such as snow shovelling or heavy lifting are not recommended as they can dramatically increase your blood pressure. If these activities are unavoidable, focus on your breathing (breath out on the exertion) and if possible ask for assistance.
Participating in a regular, structured exercise program can cause blood pressure to decrease by 5-7 mm Hg and this can occur as early as 3-4 weeks after introducing a new exercise routine.
Talk to your doctor before starting a new exercise routine.
