Sore Thighs and Scale Frustration

Yep, I made it to the gym again! I did a full 15 minutes on the bike (at Level 4, pretty good resistance) and 5 minutes on the elliptical. I noticed that these two machines work basically the exact same muscles in my thighs--and they ache right now. I think the 15-5 routine will be good for awhile until my body is ready to do more.

I got on the scale today and I nearly threw it out the window. Last week I was 410.4, and for some reason, I was 414.8 tonight. How? I haven't been eating much crap, I haven't been snacking, the only thing I drink is Crystal Light, and I've worked out the last 3 days in a row. How did I gain almost 4.5 pounds in less than a week? I hope it's just something weird with my scale, because otherwise I'm going to be really ticked if I worked so hard and GAINED weight. Yes, I know that 3 days of 15-20 minutes of exercise isn't going to drop much, but I shouldn't have gained anything, at least. WTF?

I'll weigh in again tomorrow, I think. I have my fill tomorrow too! Hurray for a protein shake for lunch.
