This study will investigate the effect of pre-operative exercise on hemodynamics in the fistula artery and vein, Pre and Post Arteriovenous Fistula Formation as well as the suitability of Cannulation of Arteriovenous Fistula at 12 weeks Post Surgery. This is a randomised control study with 20 patients each in the Control arm (Group A) or the Exercise arm (Group B). The subjects will be randomised into 1:1 into one of the two groups. The patients will have an ultrasound doppler vein mapping done prior surgery and the necessary follow up visits.
