Why do I feel 8months pregnant?!?!

I recently started C25K(only on W1D2 actually) and I wasn't as sore as I thought I would be. The only thing that hurt really were my hips. Today I completed the second day, and was walking back home and felt like I was waddling! The same waddle you get at 8 months pregnant as your hips are being pulled apart like a wishbone...yeah that's what I feel like! It's not as excruciatingly painful as that, BUT it's still pretty sore. Anyone else experience this?
