What really helped me was changing my mindset. I make exercise part of my day - part of my schedule. I figured that if I couldn't set aside 1 hour (or whatever time period) in a 24 hour day for myself, there was a problem.
I used to always have the mindset of "I hope to fit in a workout after work" or "I hope to get up early enough in the morning to do a video". When I was asked to go pick up this or go do that errand, my response would be "well....I was going to workout, but OK" or I would do the errand and then think "I will now have to cut my workout down to 30 minutes or double up tomorrow." etc.
Now my response is "No, I can't" (because I have a scheduled workout). I make it part of my schedule like a shower, brushing my hair, eating meals, etc. When I am asked to do something or have something else to be done, I schedule it AROUND my workout. Just like I would schedule appointments or errands AROUND my work schedule.
Sometimes I can't get to all my chores - but I realize it is OK to let the dishes sit out or the laundry to stay unfolded a bit longer. I believe it is better to workout and leave the laundry undone than to have folded laundry and to have NOT worked out.
Previously, I would "squeeze" in a workout after everything else in my life was done...causing me not to workout reguarly. Now that exercise is part of my schedule, I rarely go a day without it. I would never have "squeezed" in going to work after my laundry was done, so why was I "squeezing" in exercise after the laundry was done?
Good Luck - hope this helps.
