I have often had the discussion with some friends who work out as I do and have mentioned that due to exercise I have no butt. They all say the same thing you need to do squats with weights to perk up your butt. I do some squats with 8 lb dumb bells, but I also do lunges and the step. In this article, Are Squats the Best Exercise to Target the Glutes? The fact that squats with weights is the best is put to the test.
However, I keep in mind that everyone is different and what works well for one person may not work so well for another. We need to do what works best for us. So, if those squats are giving you the glutes you want, don't stop doing them.
