I am classifying this as using more than 3-4 yards of weight upwards.
Here are two ways to add the weight you need.
The former will give you better control but if you want to go very heavy then you are likely to need some element of the latter.
If you are accelerating your arm through the line then think about your sequencing if you step as this will change when you reach your release point. Ideally to keep the best control you still want your release point to remain the same.
If you don’t step, then the increase in weight may be a bit more limited but keeping that timing of the release remains just as important.
Top Tip: Practice on either hand on an end rink towards the ditch using a mat turned sideways as a target. Try different weights and body positions to hit your lines. If it is a short distance then your feet may need to point across your line to stop you being wide.
