The apartment I moved into last month has a small, but well equipped gym in the basement. I went down last night to try out TRX for the first time ever

My legs are okay this morning, but holy hanna my arms, specifically triceps, are feeling it 12 hours later. Usually it takes 24 hours for DOMS to hit. I think by that time tonight I won't be able to lift my arms at all. I'm actually finding it a little difficult to type right now.
