Can you suggest some heart exercises that i can do after open heart surgery?

Aerobic: Aerobic exercises (such as walking) are preferred as opposed to resistance exercises (such as weightlifting). Exercise does not improve the strength of the heart but improves the efficiency of the rest of the body so less demand is placed on the heart. In most cases, cardiac rehabilitation is available either as an inpatient or outpatient after heart surgery.

Walking: The easiest and safest exercise is walking, but consult with your cardiologist before starting an exercise program and periodically afterwards.
