If you find front squatting with the clean grip painful or simply don't have the patience to develop the flexibility for it, try attaching a pair of straps to the bar.

By using straps, the front squat can be more comfortable and ultimately more productive, allowing you to focus more on the exercise.

The act of pulling on the straps keeps your elbows up by acting as a proprioceptive tool, making it easier to maintain the rack position.
