I want to keep exercising every day, but after finding a job, I am too tired to exercise any more and become lazy.
First of all, you are not a professional athlete and need to work to support yourself. Exercise and fitness should become a person's hobby of running. If exercise and fitness become a burden, nothing can be done well. In the case of not delaying work, you can try to exercise slowly for a short time and gradually increase the duration, so you will feel less hard.
