This group will receive Abdominal hypopressive exercises. Each AHT will be repeated 3-5 times with 1 min rest between exercises (shift to new posture, lying,sitting and standing). Between 6 and 15 hypopressive exercises (HEs) will be performed within each session based on the participant's mastery of the exercises and readiness to progress, for 6 weeks.

This group will receive general exercises (Bridging, knee to chest, Straight leg rise) these will be repeated 3-5 times with 1 min rest between exercises. Between 6 and 15 repetitions will be performed within each session based on the participant's mastery of the exercises and readiness to progress. Each exercise to be repeated 3-5 times per set, and participants will be asked to perform technique once daily for 6 weeks

Active and specific Therapeutic exercises will be used to treat postpartum low back pain in this study. AHE consisted of exhaling to their expiratory reserve volume, then holding their breath (apnea), and expanding their rib cage, to draw their abdominal wall inward and cranially without inhalation. Each exercise will have a specific frequency, intensity, and duration.

The pain score was assessed using the numeric pain rating scale (NPRS) is a scoring system, wherein the pain level was quantified on a scale of 0 (no pain) to 10 (worst possible pain). The NPRS is a valid and frequently employed method of musculoskeletal pain assessment.

It is self-report mobility scale designed specifically for the pregnant women. The internal consistency (Cronbach's alpha) is 0.8 or higher indicating a good construct validity. The assumptions that the Pregnancy Mobility Index scores increase during pregnancy and decrease after delivery and that women with back or pelvic problems scored higher on the Pregnancy Mobility Index domains than women without back or pelvic pain were confirmed, indicating a good criterion validation.

Its scores range from 0 to 100, in which 0 equals 'normal performance' and 100 indicates 'maximum disability

It is a sixteen-item scale, which is a valid and reliable instrument for postpartum QOL assessment. It includes items on the different aspects of postpartum QOL and can be used for the early diagnosis of impaired postpartum QOL. The QoL score ranges from 0 to 30, with higher scores indicating higher QoL.

The Oswestry Low Back Pain Disability Index is a validated, 10-point patient-reported outcome questionnaire. It is considered the 'gold standard for measuring disability and quality of life (QoL) impairment for adults with low back pain. The Cronbach-α for the ODI is 0.75. The ODI showed excellent test- retest reliability (intraclass correlation coefficient = 0.91)
