Commitment to a workout schedule is an amazing feat. Being consistent every day requires dedication. However, there are times when it is beneficial to change your workout schedule to accommodate yours lifestyle. That doesn't mean skimping on your workout or not being as dedicated, it only means adjustment to make it easier to accomplish.
Some people work out in the morning and get it all done in one shot. They wake up early and then head to the gym at 5 in the morning. Good for them they can do that.
That doesn't work for everyone. If you have kids and need to get them to school it isn't going to work well. The other option is to do it during your lunch hour. That works for some if they know when they will have lunch.
Others do it at night and this works for many but sometimes it can get in the way of other activities that are going on. That will mean flexibility is important.
It is also possible to split your workout by doing a little walk at lunch and then a bigger workout at home. Depending on your goals you can adjust the type, place, and time as you see fit. The biggest thing is to keep doing it and making it a consistent activity in your life.
