There is never enough time. This is the most lame excuse I have ever heard for not working out or excercising. I am father of two beautiful little girls and husband to a gorgeous hardworking wife. We live a lifestyle where she works four nights during the week which leaves me to be the stay-at-home dad in the evenings. I can find enough time in my day to get between 60-100 minutes of excercise each day. The key is to set a schedule and make it a priority. Why should it not be a priority? I mean its your body and your life right? If you feel like you can not find the time to workout, stop what you are doing, sit down, grab a piece of paper and pencil, and write down your schedule. 
Make your routine part of your schedule and stick to it. If other things come up, figure out a time to do that and/or schedule it on your “rest or off day”.
If I can find time to fit 60-100 minutes of my time for fitness I am 110% positive that any of you out there that are single can find PLENTY of time take care of your body and your health. If you are a married couple and you are both home together in the evenings, work out together or take turns. The kids will see your example and know that staying in shape is a important part of your lives. They will learn by your example.
MAKE THE TIME
