Glomerular filtration rate is the rate at which the glomerulus (a microscopic part of your kidney) is able to filter your blood. It is generally calculated using the Cockroft-Gault formula based on your creatinine level (a product of muscle breakdown that is part of routine blood work) and your age and weight.
The muscle clean is very similar to a hang clean, except the bar sits in a higher position above the knee.
