Just go with the excuse of being pregnant...they'll understandI hear ya on that. I'm going to be around friends tonight, and its a little difficult to not drink, and then to come up with a good excuse why I can't
But in all seriousness, if your friends know the lifestyle you live, they'll understand - doesn't mean they won't still give you s#it for it, but they'll understand It doesn't have to be "cycle" related, just if you're trying to better yourself and don't want to lose any ground.
Good numbers there, bro.
