Learning how to work out

So P.E. today was very interesting, our class had to join mr. Peterson's grade 12 class and pick a grade 12 buddy. So my buddy was Thomas and when we went to the weight room I used the dumbbells. He said that anything with curls will help your biceps, along with a motto "Curls for   Girls". He tought me how to use it properly. I actually learned something new today, and I also want to continue using dumbbells.
