I once saw a coach training a hockey player on lunges.
He said, « When you stand up, push a bit sideways with your front leg to mimic your skating stroke. »
Doesn’t seem like bad advice… except that the athlete was 12 years old.
The kid wasn’t even able to stay stable when going down into the lunge. His front knee was caving in and his torso was bent so far forward it looked like he was doing a good morning.
Sure, if he pushes slightly sideways it might mimic his skating stroke. Sort of. Maybe.
