Gym closed? The floor in your room still works. Hard times remove options, not effort.

Losing the usual setup removes convenience, not ability. The plan you had was one route to something you actually wanted, and mistaking the route for the destination is what makes a closed door feel like a full stop. Effort is portable in a way that equipment is not. Fewer options only means the remaining ones need using.

Once circumstances take your normal method away, name the thing underneath it that you were really after. Find the plainest possible version and do that today. Keeping a habit alive matters more than keeping it ideal.
