Heart Rate Circuit:

Circuit training
verb. 
a form of body conditioning that involves endurance training, resistance training, high-intensity aerobics, and exercises performed in a circuit, similar to high-intensity interval training. It targets strength building and muscular endurance.

Circuit training is very time efficient which makes it a popular method of training. It is an excellent way to improve cardiovascular fitness and muscular strength endurance. It will elevate your heart rate and keep it high through the entire circuit due to the short rest periods, large muscles being worked together and a combination of upper, lower and whole body exercises. An appropriate exercise selection and structure to the circuit will mean that you can move from one exercise to the next without undue fatigue. Circuit training has some of the benefits of cardiovascular training and weight training but will not replicate either one specifically.
