Which is better...Dumbbells or Kettlebells?

If you want to build muscle put down the kettlebells girls. If your goal is to look stronger, dumbbells are superior," says Bill Campbell, Ph.D., director of the Performance and Physique Enhancement Laboratory at the University of South Florida. Moves like a dumbbell curl or press are more effective at stimulating type II muscle fibers, which leads to an increase in muscle size. When you do kettlebell specific exercises like swings, you use momentum as well as force. While these calorie-burning moves do use type II muscle fibers, they primarily activate type I fibers, whose main function is improving endurance  - not growing muscle. Doing both? You go girl!
