When you're in a rush or you have limited time to hit the gym, circuit training is a great tool.
In circuit training, resistance and aerobic training are combined into one workout to increase heart rate and keep it at a training level for the duration of the exercise session. The results are improved cardiovascular and muscular endurance along with functional strength and fat loss.
