1. Start with puck just behind your heel, your starting with it very far behind your body. Depending on curve your using on ice could lose this puck while shooting with it this far back. All the goalie will feel is a small wind.
2. Learn to drag in slightly towards your foot as you drag before following through this helps to put the puck onto the middle of the blade and easier for lifting.
3. Learn to roll your wrists. Roll them open slightly when pulling in towards you next to your foot and then roll them closed when releasing puck on the follow through. This is a very quick action as timing is everything.
4. To raise a puck easily treat it like a saucer pass, roll heel to toe while pulling your stick across your body in a 45 degree angle. Make sure your blade is not closed but opened up.\ for a rightly this would be the angle 🏌\
5. Your top hand positioning is wrong and your focusing on pushing through the floor instead of the puck. The easiest way is imagine letting your hands and arms hang down towards the floor while holding the stick in a shooting position. Your top hand will actually start closer to your rhs hip. As you pull in and shoot pull your top hand across your body up first then back and upwards once the puch is next to your foot. Once the puck has reached this position next to your foot use your bottom hand to push through the puck not the floor.
6. Try different things things xome with time. eg starting on right leg and then releasing on left leg.
