We recommend moderate-intensity continuous aerobic exercise training (eg, brisk walking, jogging, and cycling) at rate of Borg Rating Perceived Exertion (RPE) scale 3-5, 65%-85% maximum HR, or 50%-75% of peak VO2 in patients with HF.
(Strong Recommendation, Moderate-Quality Evidence)

Values and preferences: This recommendation places a high value on using commonly available measurements to assist in developing the exercise prescription. The priority is safety, hence, if a patient has a history of ICD discharges, exercise should be avoided if a short loss of consciousness is dangerous (ie, during swimming and activities associated with an increased risk of falling).
