"Great! Now, the main thing to remember is you're aiming for isolating your movements, so try to keep your ribcage still even if your hips are moving. Right? So -- we'll start off by straightening one of your knees," Dionysus is demonstrating as he talks, "Keep your heel on the floor, just straighten your knee out, and imagine there's a string pulling your hip up toward your ribs. Not going back, just going straight up. Then bend that knee back down and do the same on the other side."
