<s>[INST] What Type of Exercise Is Best for Someone With Heart Failure? [/INST] Physical activity is a great way to strengthen your heart, improve blood circulation, and raise your body’s ability to use oxygen. Depending on your health, you may need to avoid certain activities, so ask your doctor when is the right time to start exercising. You’ll want to start slowly and rest when you need to. Be on the lookout for signs you’re pushing too hard (for example, shortness of breath, dizziness, or really fast heart rate). Walking is a good form of exercise. Other activities like swimming and stationary cycling may also be good fits. Source: WEBMD. Link: https://www.webmd.com/heart-disease/heart-failure/answers-about-heart-failure. Field: Cardiovascular.
