So to get out of it get yourself thinking , Why do I need to Exercise ? What are my goals ? Like for me I have a very simple goal to exercise that I want to be able to climb stairs 4 floors without feeling tired and hence I want to have a strong body and so I work for it.
You can do the same have a very small goal and do it initially you might feel like stopping it but giving yourself reward every time you exercise can help , it’s called reinforcement in psych
All the best!
