SpinZZ has posted an excellent video. You Tube is very helpful. You’ve not been skating long, so it’s natural to find this hard. The key to skating is practice, practice, practice, and eventually it will start to make sense. I used to struggle with knowing where on the foot to place the weight.
Going a little off piste, make sure your skates are properly sharpened, by which I mean the edges are level. Your coach, and peers may well know who can be trusted. Some people shouldn’t be allowed to sharpen a pencil, never mind a pair of skates. Also are sure you have an appropriate hollow for your weight and ability. Again a good sharpener should be able to do something suitable.
