Animating Deformers

Please help! The last couple of times I have finished animating the keys for deformers (both times on arms) When I add motion keyframes to see the whole motion they change the part of the character that has deformers on and skews and twists in extreme directions before getting to the keys I’ve set for the motion its super frustrating and I have no idea what is causing this!

…Please, can somebody help!!!

Thank you!!! :bigsmile:
