Anaerobic conditioning circuits train what’s popularly referred to as the lactic acid energy system. Training this energy system is a must for those who need power endurance, ie. mixed-martial artists.
It’s also a good circuit for people who are short on time and want a tough workout that will help them stay lean and fit.
The aerobic energy system also gets a training stimulus, albeit not to the extent that a 10 km run would develop it, but it still gets worked and will improve, keeping your heart healthy.
