Too much?

Pandasarecool

For some reason, 30 day shred level two seemed harder today than it was yesterday. Was it because I didn't eat too much for breakfast, because I wasn't really hungry? Maybe I am just going too hard too soon. Or maybe I am just tired. Anyone else have this problem? Should I try level one for a few more days? Am I overdoing it doing 30 day shred AND be fit in 90? be fit is 35 minutes long and 30 day shred is 20. Let me know what you all think! Thanks! Also, sorry for being so pesty , but I figure the more I learn, the better I will be at this when the time comes to leave MFP.
