weighty matters

I don't know exactly how this works in the world of physics, but I'm almost positive that the weights at my new gym are heavier than the weights at my old one. I'm so frikkin' sore from going to the gym for the last three days. I feel like I'm bordering on quadriplegic status here. But the thing is, I didn't lift any more weight than I normally do. I didn't do any more repetitions. I did the same routine I was doing when I left my old gym. I know one measly week off couldn't have taken that big a toll on my endurance.
