I am looking for tools and procedures to keep track of changes in sizes of muscles. (or groups of muscles like upper arms and chest). (1)
How feasible is this? (2)
Are more subjective measures like photos better (3)
Can it be done without considering fatness? (4)
I am planning to measure fat in multiple locations with a caliper, and calculate total body composition at the same time. Ideally I would like to combine the numbers.
