@nicee. I encourage you to do whatever you can when you feel up to it. It doesn’t matter how intense you workout. It matters that you keep moving. It’s so good for your body and brain to stay active. If walking is good, walk. When I was undergoing treatment, I just stayed out of the gym. When I first went into remission, I hired a trainer that could push me at an appropriate pace. A trainer will help your motivation in the gym. Three years in remission and I will never be what I used to be physically, but the progress I’ve made since Cancer is phenomenal. Now, put on your tennis shoes and get walking. Good luck
