Sitting , walking standing animations for that can be edited (i'm a beginner)

hi! i have been trying to create my own walk today, and am finding alot of trouble because i am very new at animations. i would really like to find a walking animation sitting
animation and any other animations that are free to edit and to use to create your own animations (it is much easer for me to edit one to get it to the type of walk or sit that is a basic walk then to create all of the movements because i am still learning) . any animations that can be freely edited would be very welcome. thank you for reading and i hope you have a good day. bye!

You can download the generic animation files here and open them in programs like qavimator and edit them. You will have to upload them to get them into SL.
