Today i worked out my bis/forearms, and had a really good/intense workout. i did: 3 x 10 DB curls. 2 x 10 EZ-bar Curls 3 x 10 Hammer curls 2 x 10 Preacher Hammer curls 3 x 10 forearm (pronated grip) BB curls i cooled down with a few concentration curls as well. i did all that with weights that i could barely lift on my last couple reps but my muscles feel fine right now. The only time i have sore muscles is after my peck+tri days. why is this?? should i be sore right now?
