I think so. I went to my trim and tone class tonight. The instructor had us doing jumping squats, where it is kind of like a jumping jack, only squats with it. It hurt.....quite a bit. And the rest of the session, I was running on less cause I hurt my knees in this process. I'm 33, my knees "shouldn't" hurt from a little jumping.
Another confession? I haven't weighed myself since I was at the doctors right after Thanksgiving and I weighed in at 215. Which was 30 pounds higher than my lowest weigh in of 185 two years ago. I have been "trying" to get eating under control, but my stress at work has been at an all time high. And it seems like I can't control what is going into my mouth. It's mindless eating. And it needs to stop. The good news of all this? I have been working out regularly.
