Tomorrow is going to hurt

I FINALLY went back to the gym today. I haven't gone in about 6 weeks. I can barely type this from the hand tremors.
That's my biggest problem with fitness; I'm inconsistent. I'll go every day for a couple of months, then I'll barely go, or not at all, for the same amount of time.
The problem is that, when you don't go, that first week is a literal pain.
