Both groups will perform a 6-10 weeks standard exercise training programme used in the UK, 1-2 times per week. Each training session will last 1 hour. As mentioned before, the exercise programme will include cycling; walking; and strength training for the quadriceps femoris, biceps, and triceps brachii muscle groups. The physiotherapist at LCTC and its satellites will increase the work rate or duration of the exercise programme every week guided by a pre-determined schedule and driven by the patient's perception of symptoms (measured via Borg dyspnoea and fatigue scoring). It is important to note that this is not related to the increments of daily physical activity training in the PAEP (set targets of DirectLife), which will be set by another physiotherapist through Philips website.
