It's rather obvious that people who find it more enjoyable will have an easier time making a habit of it.
The only way I've found to keep myself in shape is to find activities I enjoy. For me it's dancing and rock climbing. But I had to try a bunch of things to discover that. I never imagined I would like dancing before I tried it.
Also, not everyone responds equally to exercise. Some people improve much faster than others. Some people see no progress at all unless they exercise at high intensity. Understandably it's harder to get motivated if you see little progress. I'm lucky in that, while I'm not athlete material, it's not super hard for me to gain muscle and improve my cardio.
