CBH Work and Hurt

I over-did it at Crossfit, but hope not to stall my efforts. Friday was a 21-15-9 workout doing deadlifts and pushups. Deadlifts are just lifting a bar off the ground and standing up straight with the bar by your thighs. For the workout I used 135lbs. Unfortunately, on Saturday Crossfit in Napa we also did deadlifts-I worked up to 205 lbs. I did it, but that was a mistake. My lower back(hip flexors) are trashed and it is hard to stand-up straight. I intend to run today just to stretch out.
