I may be slightly biased because I'm mostly weightlifting now... but yes, overall I feel like a heavy front squat works everything in what feels to me like a very a balanced manner. Also seems like that might be a better complement to deadlifting. Deadlift, front squat, overhead press, and some accessory pull-ups and push-ups -- seems like a great combo, though I don't know if I've ever seen a program based on this.Why do you consider front squat perhaps more useful than back for a “trained” person?
Thing I like about FS is the anterior loading. I don’t think it’ll ever not load the posterior chain but perhaps offers more balance…
