The randomized clinical trial (RCT) endeavors to enroll 50 participants, divided equally into aerobic exercise and resistance exercise groups. The study employs rigorous tools such as blood pressure measurement, SF-36 questionnaire, and the Six-Minute Walk Test (6MWT) to assess VO2max.

The randomized clinical trial (RCT) endeavors to enroll 50 participants, divided equally into aerobic exercise and resistance exercise groups. The non-probability convenient sampling technique, followed by random allocation using a lottery method, ensures a diverse yet unbiased sample. Will be conducted at the Sialkot Medical and Physiotherapy Centre, the inclusion criteria will focus on post-PCI patients aged 40-60, presenting with a BMI of 30 or higher. The study employs rigorous tools such as blood pressure measurement, SF-36 questionnaire, and the Six-Minute Walk Test (6MWT) to assess VO2max. The aerobic exercise group undergoes sessions three times a week, progressively increasing in duration and intensity, emphasizing activities like brisk walking and cycling. The resistance exercise group follows a similar schedule, engaging in full-body resistance exercises targeting major muscle groups. Both groups undergo assessments using cardiopulmonary exercise testing (CPET) to determine exercise tolerance accurately.

Inclusion Criteria:

• Age: Participants must be between 40 and 60 years old.
• Gender: Male and female both.
• Cardiovascular Status: Post Percutaneous Coronary Intervention (PCI) patients with a documented history of coronary artery disease
• Participants who are at least three months post PCI to ensure stabilization of their cardiovascular condition.
• Obesity: Participants must have a Body Mass Index (BMI) equal to or greater than 30 kg/m², indicating obesity.
• Health Status: Participants should be in stable health condition to participate in moderate physical activities.
• Willingness to Participate: Participants must provide informed consent and be willing to comply with the study protocol, including attending scheduled exercise sessions and follow-up assessments.
• Participants capable of engaging in either aerobic or resistance training, were assessed by a physical activity readiness questionnaire (PAR-Q).

Exclusion Criteria:

• Participants with severe physical limitations, disabilities, or musculoskeletal disorders that would prevent them from engaging in aerobic and resistance exercises.
• Individuals with a history of substance abuse or current substance abuse issues that might interfere with their ability to participate or adhere to the study protocol.
• Patients with Neurological diseases
• Patients with severe or unstable heart conditions, recent heart attack, or heart failure
