Wake up earlier. Sleep is definitely important for overall health and weight-loss; however perhaps you could go to bed just 30 minutes earlier, so that you could get up and work out before your day starts. Working out in the morning has numerous benefits; after all, how many times have you had the best intentions to exercise in the evening, only to have to work late, help your kids with a project or generally just feel too exhausted to get off the couch? With morning workouts, the time problem is solved!
Cut down on social media. For just a few days, record how much time you spend surfing the internet, checking personal email, watching TV, etc. Cut out some of that screen time and you will find that suddenly you have time to squeeze in at least 10 or 15 minutes of exercise into even the busiest day.
Be an active TV watcher. When you are watching TV, try to incorporate some physical activity - such as modified jumping jacks, push ups, marching in place, etc.
Make it part of your routine. One reason it's so challenging to fit exercise into a busy schedule is because we're not used to doing it. It takes time to brush your teeth in the morning, but you do it, don't you? You brush your teeth every day because it's important and because it's almost second nature to get up and do it. Start some form of exercise - whether it's walking, doing 10 minutes of yoga or going for a bike ride after dinner. Make working out a daily tradition, just like showering, or brushing your teeth. It's easy to fit in exercise for a few days here or there, but by incorporating it into your daily routine, it eventually becomes a habit.
