Circuit training was designed to perform a set amount of exercises in a row (circuit) without any rest in between each set of the exercise. In this JEFIT Dumbbell Circuit Routine, the main focus upon this routine is to build strength and increase muscle endurance but also maintaining a lean physique. You will be targeting all of the main muscle group through 8 various multijoint exercises that help strengthen and build the muscles. The key to any circuit training routine is to make sure that you do not rest in between sets or in between exercises until you complete all of the exercises in the circuit. This will keep your metabolic rate up ensuring that you burn as many calories as possible without sacrificing strength. *** Notes : When performing circuit training, you want to make sure that you are using a weight on the dumbbell that you are able to perform all of the required weight/sets and circuits that have been set. If you use a weight that you are unable to manage, you can possibly injure yourself or not get the full benefit of performing this circuit routine. Warming Up Especially for compound lifts we recommend warming up with lighter weights before your working sets. A common warmup scheme is 10-15 sets with a very light weight, followed by intermediate sets until you do 1 rep of your working weight. Reps, Sets and Rest There are many different rep schemes that'll help you reach your goals. We've set 3 sets of 8 reps by default, but feel free to change it to your own liking.
