Isolate the glute and squeeze like you mean it.
Stop at the point your glute does the work, don't overarch your lower back for more height.
On all fours, driving one bent knee's foot toward the ceiling puts a single glute in charge of pure hip extension, with the hamstring assisting from underneath. Working one side at a time means each glute earns its own reps, no dominant side quietly carrying the load. The catch is discipline at the top, the rep ends where the glute finishes, because arching your lower back for extra height just fakes range the hip never produced.
You are kicking past your hip's range and arching to compensate. Brace your core, keep your ribs down, and stop the leg where the glute squeeze peaks, the movement is smaller than most people think.
Essentially yes, both are quadruped hip extension with a bent knee driving the foot upward. Names vary, mechanics do not, keep the knee bent and squeeze at the top either way.
Slow the tempo, pause 2 seconds at the top of every rep, and add reps per side. You can also loop a band behind the knee or wear ankle weights later, but strict pauses alone keep this hard for a long time.
