Let’s be honest, sometimes our same old workout routine can not only be boring, but it is also not challenging your body because you’ve been doing the same thing for so long. Introducing new circuits can beat boredom with their fast pace and target new muscle groups to work and strengthen new muscles. This circuit focuses on building strength with five exercises, hitting the upper and lower body. Customize the circuit to the intensity that works best for you. To make it more challenging, move from exercise to exercise more quickly or boost your weight level. This circuit will help strengthen and tone while keeping your routine fresh and interesting.
