Granny Fit, Day 62 ABS

Day one of my Granny Fit work out

Day 62 of my Granny Fit work out

Seems no matter how hard I try I can't get my body into sit ups. When I edit the videos I can see that my body is shaped like a brick. I am not long and lean like a gymnast or dancer perhaps that contributes to my dilemma?
It's been 62 days since I started this work out exercise. I have for the most part avoided desert and cut my meal portions in half- yet I can not see much difference from the day one video and today's video.
I am beginning to wonder if it is possible to get fit in 100 days when you are over fifty?
The other thing I have noticed is I bloat up and have terrible gas after all my meals. I have seldom experienced this discomfort in the past. It gets so bad I almost dread eating.
The only time my body looks like the fitness work outs are having any effect is first thing in the morning before eating or drinking any thing.
