Completely agree. I was getting stronger but realized I was having trouble putting on my socks and realized I had really neglected the flexibility issue. So I took a couple steps back in weight, focused heavily on developing better flexibility, and now have drastically surpassed my previous squats weights. Plus I like not being out of breath after trying to clip my toe nails.
This was the video that I based a lot of my stretching and hip mobility stuff around... somebody posted it on a thread here before but I think its worth it again
