Testing on the 1 R.M. continuum
on knee flexion exercises (a.k.a. leg curls) show that to stay within 70 % of the maximum, you can not do more than 8 reps.. So in my opinion, leg curls done above eight reps are a complete waste of time.

On the other hand, setting your feet lower on the platform will make the move more challenging for your quads by reducing the degree of hip extension and flexion while increasing the range of motion around the knee

In addition, it's superior to traditional leg exercises because of the greater emphasis
on the eccentric component of
knee flexion and its strong carryover to the deadlift and squat.
The hamstrings are responsible for
knee flexion, hip extension and rotation
on the
knee joint when flexed.
Substitute standing rapid hip extension (hands
on wall, chest up, rapidly extend your right hip back with slight bend in your
knee, holding your TA tight so that it is pure hip
flexion and no lumbar extension.
You want to achieve a full - range of motion, which puts emphasis
on maximum
knee flexion.
Supine (Passive): Have an individual lay
on his or her's back and bring
knee into hip
flexion.
However, increases in muscle fascicle length are also likely dependent
on the mechanical load incurred by the prime mover, as
knee flexion (hamstring only) exercise seems to lead to greater adaptations in the hamstrings than hip extension (hamstring, gluteus maximus, and adductor magnus) exercise, even when muscle length at peak contraction is shorter (Bourne et al. 2016).
It is suggested that this works due to the ability of the exercise to increase the peak eccentric force of the hamstrings at shallower angles of
knee flexion (the
knee is more extended) vs. a leg curl which puts a premium
on concentric force when the
knee is in full
flexion.
Additionally, Konrad et al. (2001) found no difference in rectus abdominis muscle activity between the curl up with the hips and
knees at 90 degrees of
flexion, feet resting
on a bench, and the bent leg unanchored sit up.
