I too have the wrong shaped ears or sweaty ears or whatever and my air pods don't stay in. Now I use bone conducting headphones for working out: https://smile.amazon.com/gp/product/B08BZDTBGZ/

They are great for pod casts and only OK enough for music. They don't block your ear so depending on the volume you still have the ability to hear outside sounds. Battery life is OK, you get about 6 hours. My only complaint is that they don't fold up very small so you can't just keep them in your pocket like a pair of air pods.
