^^^ this. If you don't enjoy it you won't keep doing it.I enjoy exercising because I love running with the music in my ear, love hitting the weights and enjoy the change of atmosphere at the gym where I use some cardio equipment. Trick is to mix it up. You need to enjoy exercises. If you enjoy it, it becomes a habit.
Spend time going for walks and clearing your head.
Make sure you spend some nice evening outdoors. Nothing better than a nice walk on a summers night. Seriously, enjoy it or it becomes a chore. Don't let it become a chore.
Also set yourself challenges. Want to finish that walk 5 minutes quicker. Want to lift an extra 5kg. Little motivators
