When most people think about picking something up... they're thinking that they're initiating that movement at their hands...but that's not true. Instead, think about pushing the floor away. This will help you keep a much more stable and erect body position so your hips don't shoot first. Instead, you're going to be initiating your legs and your upper body is going to be trying to hold as stable as possible - almost like you're sitting in a leg press machine.
