Sissy Hack Squats are an excellent straight-hip quad exercise.
Keeping your hips straight allows you to take the Rectus Femoris (one of the quads - there are four, in case you missed that) through a larger ROM.

Sissy squats are named after the Greek Sisyphus myth. Apparently, pushing a bolder uphill for eternity gives you big quads. 🤷‍♂️
