Cures severe back pain too

So after yesterdays push presses, could barely walk. I let my core loose(my bad) during the presses and I really felt it in my lower back. I was in so much lower back pain the morning that I could barely get out of bed and considered staying home from work. I went to this morning's 6:30 workout and all pain went away after 10 minutes. Hasn't bothered me since too. SO happy about that. Also, I upgraded shoes. I'm now wearing converse. The problem with the keens is that they smell way too bad. I like the people at the gym too much to put them through the smell of my keens. Today we ran in our workout and they didn't suck as bad as I thought they would. My run sucked but it wasn't the shoe's fault. Todays workout was lots of fun but also hard as hell for me. Its what they call a chipper. Not because we're feeling chipper but because its one time through. I love chippers. Easier to be mentally strong on chippers. I didn't perform all that well today but I was pleased with myself for abandoning my trusty blue kettlebell(20lb) and trying some heavier ones. I ran out of my ready to drink meal replacements. I know they aren't ideal but its a convenient way to ensure I get some fiber, protein, and fat when my days get busy. I have loved the last 7 workouts more than usual. Not sure if the coaches have intentionally changed anything or if I've just found a new appreciation or if I am just feeling good. or maybe its that the class size has been capped. I also like workouts that don't allow me to slack or take the easy way out. Sometimes its a challenge to be self motivating that early in the morning. The stop watch, the tally, and the motivating coaches have been good for me. Now if I can dial in the diet, I may someday be able to fit in my pants again. :)
