Tabata doesn’t involve many risks; however, due to its high intensity, I don’t recommend it for heart patients or people with high blood pressure. This type of interval training rapidly increases your heart rate, so it is recommended that you consult your doctor before adding Tabata to your workout regime.
There is also a risk of injury when you are performing any exercise; however, this risk can increase when you increase intensity and speed. Make sure you are comfortable performing the exercises and can maintain proper form at a moderate pace before incorporating them into your Tabata routine. If you have questions about form or technique, seek out a professional trainer for advice and assistance.
