dynamic effort squats are usually used to work on form and speed, But are they also good for working on hip flexibility? I have fairly inflexible hips, and it takes a lot of warming up for me to hit about an inch below parallel with a wide stance. Is it safe for me to be working on this during DE days?
And when I say "working on flexibility," I mean usually I'll set up the weight and my box (about two inches below parallel) and squat with a wide enough stance so that its pretty uncomfortable at the bottom of the squat. I have to really keep tight and focus on keeping my knees from caving in.
Oh, and I already use one of those stretching machines after workouts, and do all sorts of hip stretches afterwards to little avail.
