Squat form check.

I am 37 years old and have been lifting for just over three years. I have only done one IPF meet, where I went 375/215/513 in the 181 class. After watching this video, I seem to be going a bit too low and I am having upper back rounding. I am wondering if this is due to bar positioning. I used to squat with thumbs over with my index finger on the rings a bit lower on the back. I started trying to bring my grip in, and now have my pinky fingers on the ring with thumbs around, but it makes the bar ride up higher on the back.

I am going to add in front squats to try and fix the upper back rounding, and box squats to fix my depth. If anyone else has some advice, I would appreciate the input.

BTW I was doing the old cms routine and swapped to the four day program when it came out. The only modifications I have made is slightly higher volume on squat days. IE I went 2 x 2 and 3 x 2 at 85% the day of the video instead of 2 x 4. The weight on the bar is 320lbs, and I weighed in at 175 just before training.

You can do front squats to a box. Come down gently on to the box too.

Overall just very loosey goosey, need to stay much tighter. That weight is not a high enough percentage to be causing the sloppiness.  Its not something that happens overnight

Your decent is too quick, which is making the weight shift in your feet and making your upper body round forward a bit.

A good drill is to bring your elbows forward and towards your torso without adjusting your grip. I eventually had to bring my grip out because my elbows were touching my thighs when I was in the hole.

I hope this helps you.
