Experimental group will be given MET Program, stretching & strengthening exercises and Hot packs (for 15 minutes). MET program will include warm up, endurance and cool down exercises. The warm up and cool down period will be consisted of 5-minute walking, and 10 repetitions of stretching exercises. Endurance exercises will consist of 4 levels.

NPRS is anchored by terms describing pain severity extremes. The 11-point numeric with 0 representing No pain, 1-3 representing Mild Pain (nagging, annoying, interfering little with ADLs), 4-6 representing Moderate Pains (interferes significantly with ADLs), 7-10 representing Sever Pain (disabling, unable to perform ADLs)

The Oswestry Disability Index (also known as the Oswestry Low Back Pain Disability Questionnaire) is an extremely important tool that researchers and disability evaluators use to measure a patient's permanent functional disability. The test is considered the 'gold standard' of low back functional outcome tools. This scale contain question related to functional activities of pain intensity, personal care, lifting, walking, sitting, standing, sleeping, sex life, social life and travelling. For patients understanding, URDU version is used.

The prone double straight-leg raise test will be used to assess participants' back muscle endurance. The participant lay on the plinth in prone-lying position, hips extended, with the hands underneath the forehead and the arms perpendicular to the body. Instruct the participant to raise both legs until knee clearance is achieved. The researcher will monitoring knee clearance by sliding one hand under the thighs. The time taken by participant to maintain knee clearance monitored with a stopwatch will be recorded in seconds as back muscle endurance

The patient is standing with his back towards the examiner. The examiner determines the location of the lumbosacral junction at the level of the posterior superior iliac spine by pressing the location of the dimples of Venus. The intersection of the top of the dimples of Venus is marked by drawing a horizontal line. This line acts as the landmark. Two other marks will be drawn 10 cm above and 5 cm below the first landmark. The patient will then be asked to bend over and touch his or her toes as long as possible without increasing pain. The examiner will measure the increase in distance between the superior and inferior marks. The length increment, which is the difference between the 15-cm distance (neutral position) and the increased distance (anterior flexion posture), will be calculated to determine the range of motion of the lumbar spine
