I go to gym 4 times a week. I do various exercise using different machines (chest press, leg press, row etc). On each of these machines I do 3 sets with 10 reps.
I also do 6 sets of bicep curls using 20 pounds dumbbells. I noticed that after using dumbbells my biceps look much bigger but after half an hour or so my biceps go back to same size where they were before the exercise.
My question is.
- Why do biceps grow so much right after the curls?
- How can i make my biceps permanently bigger?
