Fractional plates have been an absolute must for me (female, not quite 5'1", 122 lbs). I do not understand why some men seem reluctant to use them when they have that option.
I train at home and the larger plates I use are marked with athletic tape to ensure I always use the same ones on every lift. With precise 1-pound jumps, my press has gone from 58 to 90 lbs, and my bench from 88 to 129 lbs. Not sticker-club worthy (yet), but way beyond my wildest expectations about this program.
