With the Functional Range Conditioning system, we always talk about training as many different joint angles under voluntary muscular contraction. One of the newest positions I've been training Hip Controlled Articular Rotations (CARs) is through a push-up stance. While the position of these is the most challenging I've come across to date, I see a ton of merit in them when done properly.
Of course, these aren't meant for everybody due to the high demands of irradiation and multi-joint stability required. If you're able to position yourself properly however, I highly recommend giving these a shot. These Hip CARs will challenge you, but also give you a better feel on how to build sufficient tension while resisting any type of compensatory movement.
