Exercises recommended for dialysis patients include walking, bicycling, swimming and jogging. Dialysis patients may also use light weight lifting as a repetitive exercise. It is true that these exercises are recommended to be done for approximately 150 minutes per week. Dialysis patients with a fistula should not lift heavy weights that require the individual to strain and tighten their abdominal muscles while holding their breath. This is known as a Valsalva maneuver and this causes an abrupt increase in your blood pressure and is not good for your heart, your blood pressure or your fistula.
Hence, I would recommend daily walking, jogging, swimming or bicycling coupled with lifting light weights for your upper body, arms and chest. I do not recommend weight lifting, pushups, or body weight squats. I would also not recommend using any device to stimulate your muscles. Natural movements are the best exercise for your heart and your muscles.
