Precisely! If you push yourself too hard, then you'll end up avoiding it. Try to keep things to a level where you can enjoy it, and maybe explore options until you find one that's lots of fun for you. For some that can be walking, cycling, etc or even chopping colorful boxes moving at high speed in virtual reality.

Seconded. Be sure that you are having fun. This is the most important thing. If you're having fun, then you'll stay motivated, and keep building the habit!

Once you form a fun and healthy habit, then the rest will follow, and you can revise your plans based on what you like and don't like.
