Weigh In Wednesday: the Lent edition

This week I managed to lose 1.8 pounds.  As soon as it posts to Twitter from MFP, a bunch of my friends "favorite" the tweet or tell me good job. I need to turn that feature off.  Now, before we get all excited and celebrate that loss, let's not forget that I basically GAINED that much last week, so it's really a wash.  I'm still in the 150s and that's really too much, especially when you consider I maintained around 138 for so long and now here I sit, 14 or 15 pounds heavier than I should be.

sad but true

I don't doubt that my weight has something to do with the aches and pains while I'm running.  Lugging around this much weight, even though I'm running almost as fast as I was before I got injured again, surely can't be good for my knees and feet.  Plus, it's just a lot harder to run a 10 minute mile right now than it should be.  (10 m/m should be my "easy" pace, 9:40 or 9:30 my "hard" pace)
My CrossFit friends will try and tell me that I'm doing too much cardio, which isn't a belief I share.  Sorry guys. I still think burning calories is important and I like cardio.  But, I will agree that I need to add in more strength training.  
So, for the 40 days of Lent, I'm not giving anything up (because my giving up coffee or beer would be more of a hardship for those around me), but adding in something healthy.  I'm going to do at least 1 strength move every day because 1 is still better than zero in the hopes that it creates a better habit for strength training.  That move might be 10 triceps dips and squats like today, planks, pushups, lunges, bicep curls, whatever.  I'll post what I do on DailyMile to keep track.
Do you give something up for Lent or try to add in a healthy habit?
