I’ve discussed squat depth in multiple articles over the past couple of years. I’ve talked about hip anatomy HERE, and I’ve talked about buttwink HERE. But how do you know what your ideal squat depth is?

Make sure you stay planted on your heels and don’t rise up onto your toes. From there, you can determine if you want to go slightly deeper, but keep in mind that there’s only so much wiggle room and it may be best to play it safe. Here’s a video that better explains it:
