Following the consent of the participants, heart rate (HR), blood pressure, and oxygen saturation baseline measurements were taken through six minutes' walk test. The program included patient counseling on the treatment intervention and right technique, such as regular breathing patterns and avoiding breath-holding. Each session lasted 60 minutes. The targeted muscles included the biceps, triceps, and deltoids in the upper limbs, and the quadriceps, hamstrings, and calf muscles in the lower limbs, using exercises with sandbags. Exercise dosage was progressed by increasing the resistance and repetitions. Load increases were made by 5% once the participant could comfortably achieve the upper limit of the prescribed range. The protocol took total 12 weeks, with 3 sessions per week.

Duration: The program lasted 12 weeks with 3 sessions per week.

Session Structure:

• Each session lasted 20-45 minutes.
• Exercise intensity was set at 50-70% of maximum heart rate (MHR).
• Intervals consisted of 1-4 minutes of moderate-intensity exercise, followed by shorter rest periods of 1-2 minutes.

Exercise Type:

• Alternating aerobic activities targeting both upper and lower body, such as treadmill and walking.
• A warm-up (5-10 minutes) and cool-down (5-10 minutes) with light stretching and low-intensity walking were included.

The 6-Minute Walk Test (6MWT) is a functional exercise capacity test which is validated and is able to measure a patient's walking ability for six minutes considering the maximum distance covered. It reflects the capacity for aerobic activity and endurance which is why it is mostly used in cardiac rehabilitation. The test is straightforward, cheap and requires no special equipment in a doctor's office. The reliability of the 6MWT

Spirometry is a common and essential pulmonary function test that measures the volume of air a person can inhale and exhale, as well as how quickly they can do so. It helps in diagnosing and monitoring respiratory diseases, such as asthma, chronic obstructive pulmonary disease (COPD), and other conditions that affect lung function. The reliability is usually good with test results reproducibility generally being above 90%. The validity is also well-defined since spirometry is rated as gold standard of measuring the lung functioning.

Cardiac Efficiency is defined as the heart's capability to pump blood in a manner that requires the least possible effort and still guarantees the tissues receive a good supply of oxygen. The most important indicator of cardiac efficiency is Peak Oxygen Uptake (VO₂ Peak) which comes from a cardiopulmonary exercise test (CPET) that is done under controlled conditions.

The IPAQ (International Physical Activity Questionnaire) is the tool that is mostly adopted to evaluate quality of life via physical activity assessment. The IPAQ is made up of 7 queries which ask about the duration of the physical activities, very light to heavy, that happened in the last 7 days
