I hear you , Pinkie! I love to exercise once I'm about 2 minutes into the process but actually getting on the bike or treadmill or yoga ball is the hard part.
I have to say that I have been researching since last night about how many calories I burned on the stationary bike and it looks like that calorie number might have been correct. I was agog to see that a person my size can burn up to 600 calories an hour depending on the intensity on the bike.
Seems like the stationary bike really packs a good punch on the exercise. I burn twice as many calories on a 15-minute work-out on the bike than I do on the treadmill. I think I'll be hitting the BIKE a lot more!
Also, I have found that even if I tell myself "I'll just do 5 minutes..." when I am not feeling motivated that once I actually get on the bike or treadmill, I usually end up telling myself that "5 minutes is sucky so let's just do 15 and quit whining..." and 9/10 times I do it!
If you are feeling unmotivated, find a giant mirror and slip on your iPod headphones and just dance with yourself for a few songs. Dancing is super fun and burns a tremendous amount of calories. I have been dancing with myself in the library and just doing 4 songs vigorously will wear my ass out but I'm having so much fun doing it that I look forward to it the next day.
Good "Dance with yourself" songs that I've been using the last couple of weeks:
Hot For Teacher - Van Halen
I Gotta Feeling - BEP
Are You That Somebody - Aaliyah
Bossy - Kelis
Check On It - Beyonce
