Haha, I know, what I love with BSS is that I can overload the legs without necessarily overloading my back. I can also play with stance length to get different recruitment levels.
Think about it - doing BSS with 40 kg dumbbells (80 kg in total) is like doing bilateral squats with 160 kg in terms of leg stimulation. Now I realize it's more to that than just weight but still, it's just a great thing to do.
