It's easy to look at the final project, but it's important to make sure you allow yourself to have many small victories along the way. A special treat if you exercise a certain amount per week, or lose a pound or two. Always reward EVERY accomplishment, and the big picture will be the grand prize!
I gave up on the late night snacks. If I feel like I really need something, I will take a piece of fruit or some raw veggies like baby carrots, some slices of cucumber or a stalk of celery. This seems to quench the urge and keeps me on track.
I had to get creative after surgery on both of my feet. YOUTUBE to the rescue! In addition to videos for chair aerobics, I also use ZUMBA videos and follow along most of the arm movements. FUN and calories burned from the chair. Great work out.
Be VERY careful with your back when making basic movements - bending down excessively can be quite hazardous! Also, when picking up items, do not use your back for momentum (don't ask me how I know this.....)
I encourage you to take measurements and keep record in a notebook. When things don't seem to be moving along for me it is a great boost to see that one year ago I was ten pounds heavier and ten inches larger! Week by week I may not see improvement, but the big picture shows I've made progress.
My mantra has become, "If it's uncomfortable, I must be doing something right". If measuring my food and exercising aren't necessarily 'comfortable' or convenient, then that's a good sign I'm doing something right and making changes. Eventually these things will become my new 'comfort zone'.
