Aerobic interval training (AIT), which included rest intervals in between sessions of aerobic activity on a stationary bike and treadmill, was administered to the control group. A 10-minute warm-up, or a maximum of 50% to 60% of HR, preceded the program. Participants will complete a well-tested Performa. Basic parameters will be collected through the outcome measure tool. The difference in improvement before and after 6 weeks will be documented and compared.

Resistance interval training for post-coronary artery bypass grafting (CABG) patients requires careful consideration and should be conducted under the supervision of healthcare professionals, such as cardiac rehabilitation specialists or physiotherapists. Exercise programs for individuals recovering from cardiac surgery must be tailored to their specific needs, taking into account their overall health, medical history, and current fitness level. Before beginning any exercise program, it's essential to obtain clearance from a healthcare provider. The workout lasted thirty to forty minutes in total. To fit the training load, resistance and intensity were gradually raised. For six weeks, this supervised training program was adhered to three times a week on alternate days. The difference in improvement before and after 6 weeks will be documented and compared.

Aerobic interval training (AIT), which included rest intervals in between sessions of aerobic activity on a stationary bike and treadmill, was administered to the control group. A 10-minute warm-up, or a maximum of 50% to 60% of HR, preceded the program. The next activity round consisted of six x six-minute intervals of cycling and walking/uphill running on a treadmill at 60% to 85% of THR, separated by three minutes of rest/recovery. A ten-to fifteen-minute cool- down period followed the session.

The 36-Item Short Form Survey (SF-36) is an outcome measure instrument that is often used for quality of life, well-researched, self-reported measure of health. It stems from a study called the Medical Outcomes Study for the objective measure of the quality of life. The 36-Item Short Form Survey (SF-36) will be used which is a self-reported measure of health that covers eight domains of health.

The 6-minute walk test (6MWT) will be used for cardiorespiratory fitness, to measure the distance walked in a specified time and reflect the functional exercise level. The primary measurement is 6-min walk distance (6MWD), but during the 6MWT data can also be collected about the patient's blood oxygen saturation and perception of dyspnea during exertion. When conducting the 6MWT do not walk with the patient and do not assist the patient in carrying or pulling his or her supplemental oxygen. The patient should walk alone, not with other patients. Do not use a treadmill on which the patient adjusts the speed and/or the slope. Do not use an oval or circular track. An increase in the distance walked indicates improvement in basic mobility. Post training a difference of at least 45m should be observed for the 6 minutes' walk test to be sure that a "real" change in the patient's condition

For endurance, the sit-to-stand (STS) test measures the number of times a person can stand up from a chair in a given time (30 seconds, 1 minute, or 5 repetitions). The 30 Second Sit to Stand Test is also known as 30 Second Chair Stand Test (30CST), was initially designed for testing leg strength and endurance in adults. The score is the total number of stands within 30 seconds (more than halfway up at the end of 30 seconds counts as a full stand).The 30-second chair stand involves recording the number of stands a person can complete in 30 seconds rather then the amount of time it takes to complete a pre- determined number of repetitions.
