This isn’t an “agree to disagree” topic or “well some people are built different” discussion. You cannot grow the hamstrings with Any squat or lunge or leg press variation.

When you squat or leg press, the hamstrings shorten at the knee and lengthen at the hip. On the concentric they lengthen at the knee and shorten at the hip. So their relative length never changes.

In order to get a high degree of intra-muscular force a muscle needs to lengthen and/or shorten dramatically in comparison to its resting state. There is literally no way to do this with leg presses or squats when it comes to hamstrings
.
Squats provide so little stimulus for hamstring growth that even in noobs, there was no real hamstring adaptation to squatting (Kubo 2019 study) .
