Tight calves and shit squats?

The squat is a popular strength exercise, second only in popularity to the deadlift. However, many adults have trouble performing full range of motion "ass-to-grass" squats because they have tight calves, which limit ankle dorsiflexion.

Not only does this affect our squats, but it also affects lunges, step-ups, pistol squats, and even our forward fold (pike and pancake) flexibility.
