Does your dance teacher or coach constantly yell at you to straighten your legs, but you swear they are as straight as they can be? Well, you might be right- you might have hypoextended legs.
Hyperextended: Hyper- too much (over)
Hypoextended: Hypo- not enough (under)
However, this is NOT an excuse for dancing with visually bent knees. You can improve the ability of your legs to fully straighten using these workouts.
