I know that if want to focus more on building the hamstrings and glutes then I should do the long-stride version because A long-stride lunge where your propulsion point is the heel will be a very hip-dominant movement. However, when doing dynamic or reverse lunges does it matter if your stepping is a little off? For instance, whenever I do barbell dynamic lunges I sometimes accidentally step forward a few inches more than I need to and sometimes when drive back off the heel to start position I accidentally end up having that foot end up being placed a couple to a few inches ahead of the other foot.
Nope that doesn’t matter too much.
