I walk everyday and need to add something to it. I have needed to do that pre-Covid, and especially need to do so now. I am not sure if I want to go in the cardio direction only or if weights/core would be more helpful. Ideally there could be some combo of both, but especially the weight/core part needs to start at the beginner level. In the past fitness blender has been recommended and I never tried it. Is this still what you all would recommend? Anything else?

Thanks!
