I finally did a deck squat with perfect form and no stumbling backwards at all!!

I was ready to write off ever hitting perfect form due to my size (6'1 260lbs), but hopefully this can be a testimonial for the bigger guys or anyone still struggling with this element. And I've noticed with good form, this element becomes easier. I even did an extra set today because I felt I had a lot more energy with the good form.
What helped me the most was holding a deep squat in the hole for about 10 seconds as part of my warmups and really concentrating on the weight shift forward before standing up.
No more big guy excuses here...feels great!
