The Frog with feet in straps is a classic exercise. It can be done on the Reformer as well as the Cadillac and the mat with a theraband. This exercise is meant to strengthen the midline of the body by using a bent and extended leg. A neutral pelvis is key here. You don’t want the body to rely on gripping the glutes to complete the task. Also, you want to be sure that external rotation of the femurs here is uniform and easy. A lot of times a good deal of release work needs to come before an exercise like this so that the femur can sink deep into the pelvis during the work.
