The best solution is to break time into easy chunks. Doing a 10 minute workout session is better than nothing. Or a number of 10 minute sessions.

Another technique is to start small. For example, start with 10 minutes. If you feel like you can do more, then do so. This is a great way in general to get going on projects and not procrastinate. It is based on the concept that the biggest hurdle often on a project is just getting started.

Once one realizes they will.get something really good out of their exercise program if they put a lot in, things can change.

As you know, gyms are crowded often in January and then emptier by March. The reason is that it is easier to start a new project than to create a new long term habit.
