A remote controlled blood flow restriction cuff comprising: an air bladder configured to be positioned around a limb; a compact air pump located on the cuff to pressurize the air bladder; a pressure sensor to sense bladder air pressure; an electronic controller to control operation of the air pump ; the controller adjustable for a predetermined pressure or pressure range, and receptive and responsive to signals from the pressure sensor ; a power supply located on the cuff to provide power to the air pump , controller and pressure sensor ; wherein inflation and deflation of the cuff can be controlled using a remote device in communication with the controller wherein the electronic controller is configured to: inflate the cuff in small increments until pulse stops; sense at what pressure level pulse rate is no longer detected using photoplethysmography, bioimpedance, near infrared spectroscopy and/or Doppler ultrasound, determine a limb occlusion pressure (LOP) of a user as the point at which minimal pressure is required to stop blood flow to an extremity of the limb; inflate the cuff to a desired percentage of LOP between 50-80% based on a user selection; and to maintain the pressure at the selected percentage of LOP, keeping pressure constant in this zone allowing for adjustments with limb/body movement. an air bladder configured to be positioned around a limb; a compact air pump located on the cuff to pressurize the air bladder; a pressure sensor to sense bladder air pressure; an electronic controller to control operation of the air pump ; the controller adjustable for a predetermined pressure or pressure range, and receptive and responsive to signals from the pressure sensor ; a power supply located on the cuff to provide power to the air pump , controller and pressure sensor ; wherein inflation and deflation of the cuff can be controlled using a remote device in communication with the controller wherein the electronic controller is configured to: inflate the cuff in small increments until pulse stops; sense at what pressure level pulse rate is no longer detected using photoplethysmography, bioimpedance, near infrared spectroscopy and/or Doppler ultrasound, determine a limb occlusion pressure (LOP) of a user as the point at which minimal pressure is required to stop blood flow to an extremity of the limb; inflate the cuff to a desired percentage of LOP between 50-80% based on a user selection; and to maintain the pressure at the selected percentage of LOP, keeping pressure constant in this zone allowing for adjustments with limb/body movement. inflate the cuff in small increments until pulse stops; sense at what pressure level pulse rate is no longer detected using photoplethysmography, bioimpedance, near infrared spectroscopy and/or Doppler ultrasound, determine a limb occlusion pressure (LOP) of a user as the point at which minimal pressure is required to stop blood flow to an extremity of the limb; inflate the cuff to a desired percentage of LOP between 50-80% based on a user selection; and to maintain the pressure at the selected percentage of LOP, keeping pressure constant in this zone allowing for adjustments with limb/body movement. <EOS>
