I could never make 10k steps routinely until I started jogging. Download the Couch to 5k (c25k) or couch to 10k/half-marathon/marathon and follow the fairly gentle introduction to running. You will hit 5k steps from the easiest runs and get to one hour walk/runs which can be 8k+ steps after a couple weeks. It's so so much easier than trying to just walk and honestly becomes fun after a couple weeks of sucking
