SOPP315: I’m struggling with the pedal exercises

Let’s start episode 315 of Secrets of Organ Playing Podcast. This question was sent by Dianne and she writes: “I’m struggling with the pedal exercises that call for playing a fourth with heel and toe of one foot... And doing so legato without playing pedals in between. Some of the 3rds, depending on octave and foot called for, are difficult as well. My feet don't bend and stretch that way!”
