Plant your feet and pump out reps in place.
Drop straight down, not forward, keep your front shin vertical the whole set.
Dropping straight down in a fixed split stance loads the front-leg quads through a deep knee bend while the glutes control the hip and drive you back up, one leg carrying the bulk of the work at a time. Because your feet never move, there is no balance juggling between reps, just clean tension on the working leg. That makes it the ideal entry point to single-leg training and a reliable finisher when your legs are already cooked.
Practically nothing, they are two names for the same pattern, feet fixed, lowering straight down. Walking and reverse lunges are the versions where a foot travels each rep.
Some back-leg work is normal, it stabilises and its hip flexors get stretched at the bottom. If the back leg is doing most of the work, shift more weight through the front heel and check your stance is long enough.
Start static. No stepping means better balance, cleaner depth and easier progression. Once static lunges feel controlled, walking lunges add the coordination and glute demand of stepping through.
