Study them as layers . Start by memorizing how many muscles are in each layer then memorize there names(sometimes the name is related to the muscle's shape or action or sometimes its origin and insertion) then study thein origin and insertion(for me i do a schematic drawing of the bones and start adding the muscles to the pic) try memorizing there order from left to right if they're in the same layer )some areas have mnemonics .always use a good reference i use greys anatomy) .so thats my way i wish it helps ❤best of luck dr.
