In abdominal obesity the vertical chest diameter is decreased due to upward abdominal compression on the diaphragm where it can{u2019}t descend completely down ward during contraction affecting respiratory function such a way that it has an impact on daily practices. To investigate the efficacy of aerobic exercises in the form of treadmill and bicycle on vertical chest diameter and compare the effect of each. A pre test post test two by two experimental groups design. 30 female volunteers with abdominal obesity (waist circumference ( < 88cm), aging from 20 - 40 years and body mass index ( > 30 kg / m2) participated in this study. They were assigned into two equal groups of 15 female; group A received treadmill program and group B received bicycle program. The study lasted for 12 weeks at a frequency of 3 sessions per week. Body mass index (kg / m2), vertical chest diameter (cm) were measured before and after treatment program for both groups
