Forward lunges hit your quads harder but stress your knees more. Reverse lunges engage your glutes better and are easier on your joints. Pick reverse if your knees are sensitive or you want to build glutes.
Should you be doing forward lunges or reverse lunges? Well, it depends on what you're trying to work. A forward lunge is going to work a little bit more of your quad, and it does typically put a little bit more pressure on your knee, whereas a reverse lunge is going to work a little bit more of your glute, and it's going to take a little bit of pressure off of your knee. So if you don't have knee issues and you want to work more of your quad, maybe you can do forward lunges, but if you have some knee issues and/or you want to work more of your glutes, I'd probably recommend reverse lunges. Hope it helped.
