Group A:twenty patients of both sex Iintervention :moderate intensity intradialytic aerobic training for 12 weeks. (3 times per week). Using Horizontal electromagnetically braked cycle ergometer during the first half of the dialysis session.

(1) Frequency: received intradialytic, lower-limb, cycling exercise three times per week on alternative days (2) Intensity: the intensity of exercise will be at 12-14 based on the Borg's Perceived Exertion Rating Scale.(a rating of 6 perceiving "no exertion at all" to 20 perceiving a "maximal exertion" of effort) ,Appropriate speed and grade of resistance were adjusted to achieve the required intensity. (3) Time: each session consisted of a a 5-min warm-up in form of ankle pump exercises, 20-min moderate intensity exercise, and 5-min cool-down phase in form of ankle pump exercise.

Grob B Twenty patients of both sex intervention :this group will participate in moderate intensity intradialytic resistive training without medication for 12 weeks . (3 sessions per week) using ankle weights.

During session: The warming up phase for 5-minute in form of ankle pump exercises, then the main exercise phase and then cooling down phase for 5 minutes. in form of ankle pump exercises.

The training protocol consisted of five lower-body resistance exercises using ankle weights 3 days/week, The intensity of the program will be moderate, starting with two sets of each exercise at 60% of each patient's three repetition max (3-RM) strength, progressing to three sets per session, with additional weight added as tolerated.

twenty patients will participate in moderate intensity intradialytic aerobic training for 12 weeks. (3 times per week). Using Horizontal electromagnetically braked cycle ergometer during the first half of the dialysis session.

(1) Frequency: received intradialytic, lower-limb, cycling exercise three times per week on alternative days (2) Intensity: the intensity of exercise will be at 12-14 (moderate-intensity: somewhat hard or reports of feeling a little bit tired but still ok to continue) based on the Borg's Perceived Exertion Rating Scale Appendix III (a rating of 6 perceiving "no exertion at all" to 20 perceiving a "maximal exertion" of effort) ,Appropriate speed and grade of resistance were adjusted to achieve the required intensity. (3) Time: the duration of each exercise session consisted of a 5-min warm-up in form of circulatory exercise.

aterogenic index will be measured through blood test ,an AIP value of under 0.11 is associated with low risk of CVD; the values between 0.11 to 0.21 and upper than 0.21 are associated with intermediate and increased risks, respectively
