Do you consider exercise a priority? A good way to answer this question is to keep a log for a few days and see what you spend your time on. There are many distractions in our lives but exercise should not be a distraction, it should be part of your lifestyle.
Once you have listed the ways you spend your time it might become obvious that you are able to squeeze in some exercise time. If you find that your schedule is actually too full then consider swapping something out. Like maybe a half hour sleep or watching TV.
Ultimately it's your decision on how important exercise is in your life. Even little amounts of exercise accumulate and have a positive effect on your health.
