I used to do lunges but I got strong enough at them that it would tweak my back and/or sprain my big toe on the back leg. I am pretty sure the toe thing is just bad form.
I think heavy lunges are actually a very advanced exercise, since you need to place the lead foot almost perfectly to get a good repeatable rep with good mechanics. Also, there is more impact. And yeah, I get the toe thing too.
SSB Bulgarian Split Squats. With hands free you can reach out and touch the rack for balance while banging out reps. Deeper than lunges so big training effect
If efficiency matters at all to you, then yes, traditional squatting has benefits over single-leg movements. If coordinated effort between both legs simultaneously has any relevance to your goals, traditional squatting has benefits. If developing maximal overall strength has any relevance to your goals, then traditional squatting has relevance. You will come across limiting factors outside of leg strength itself if you avoid squats altogether. There is only so much weight you can reasonable hold in your hands performing split squats and pistol squats. You also have to dedicate far more effort and training energy towards balance when performing single leg movements, that could otherwise be directed simply at moving heavy weights.
The bottom line is that if your goals are quite modest, you can likely get away with just single leg movements. I don’t see very many, if any, goals you could have where traditional squats wouldn’t benefit you, but all that means is that you’re likely taking a less efficient path to your goals, you may still get there.
Very true, I didn’t think about this much
Makes sense. Cheers for writing such a helpful post
