If you have high blood pressure and you want to include weight training in a fitness program:
Learn how to lift weights to reduce the risk of injury.
Do not hold your breath. Holding your breath during physical exertion can cause dangerous spikes in blood pressure. Instead, breathe easily and continuously.
Lift light weight more times. Heavy weight requires more voltage, which can lead to a greater increase in blood pressure. You can strengthen your muscles with lighter weights, increasing the number of repetitions.
Listen to your body. Stop immediately if you are very out of breath or feel dizzy, or if you experience pain or pressure in the chest.
