Gela Allmann - 15 Minuten Core Workout

[@mirjamkarres8055]

Hi Gela, I really like your video's! It inspires, and gives me inspiration for the holidays in the mountains!! I have a question. Sometimes I have troubles with my knee when I'm descending from high altitudes. Do you have suggestions how to workout or training advice.? Thank you so much, regards Mirjam from the Netherlands
