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. Hinge back slightly and use a short, explosive hip action to accelerate the bar vertically and rack it on the shoulders. The arms do a fair amount of work to muscle the weight to the shelf position.
What muscles does running work? Running works the quadriceps, hamstrings, gluteals, hip flexors, abs, calves, tibialis anterior and poroneal muscles. Although the exercise does not build these muscles or make them stronger, it does make them capable of greater endurance.
