Muscle shape and cuts

[WannaBPowerful]

Been seeing this a lot in articles latly. Higher reps and a bigger stretch makes the cuts between the muscles deeper? Someone please explain how this is true???? Was said in a Cutler article, and twice in two others (no idea who they were by).

It's not true, as far as I know.

If you believe in POF - contracted positions will carve "deeper" cuts and stretch will elongate the muscles - aka pilates

Any more information/opinions/theories on this? Would like more feedback. Maybe some insight on how you would train for deeper cuts and seperation.
