You might find it more effective to begin your snatch or your clean with your toes pointing slightly out instead of straight ahead. The positioning of your toes will change the positioning of your hips and shoulders.
(Apparently), many lifters see quick technique improvements when they point their toes out in the starting position of their snatch and clean.
Have a go and see if it improves your lifting. You can experiment with the angle of your toes – from very slight to more extremely pointed out (it may take anywhere from a few reps to a few workouts to get used to this new position though!).
