Hey @dmpa88 Tom doesn’t work at Freeletics, so he can’t promise you anything (neither can I). But as said in this post and many others already (this one in German) Arthrose im linken Knie - #4 by Lara they won’t because the app is for healthy people only. They can’t determine what you have and thus should avoid and don’t want to go into any lawsuits because of that. You should go to a doctor or physiotherapist and talk about what exercises you should avoid or practice.
Depending on the journey, you should be able to exclude dips altogether though.
