A single kettlebell session works cardiovascular
and resistance training and is completely
functional meaning you can achieve better
results in a single kettlebell session as
opposed to a low intensity workout in a gym.
The body has two main energy systems (aerobic
and anaerobic energy system). Energy is needed
for maintenance, growth, everyday activities
and exercise.
The amount of energy required during exercise
by the body depends on the intensity and
duration of exercise.
