legs feel like lead...

My working out is going very well.
I am getting stronger and much more toned.
My energy level is great.
My weight loss has stalled but I am trying to stay positive but...

My legs feel really heavy whenever I try to jog. It is so strange. I feel as if I am retaining a lot of fluid and I think that this is the reason for the weight loss stall. Could my muscles be dehydrated with the fluid retention being my body's method of trying to address the problem? Could it be something else? Do I just keep drinking tons of water and wait it out or is there something I can do???
