I've been using the wide stance box squats and i deadlift conventionally. Now i've read articles that say wide box squats are better for sumo lifters and not lifters like me. So are wide box squats still beneficial for us conventional deadlifters?
It's good to do a combination of close stance and wide stance box squats. The close stance box squats will hit your quads more and your quads help the start of your pull. Wide stance is going to hit your hips, glutes, and hamstrings more. Pause squats and Anderson squats are also good for improving your deadlift.
