Question

What is the main difference between cardio and strength-training activities?

Answer 1

Cardio decreases your inflammatory signalling in the fatty tissue, while also preventing your body from storing too much fat, as long as you are sticking to healthy doses of cardio.Cardio also builds endurance as it strengthens your body’s circulatory system. On the other hand, strength training uses resistance exercises that contract your muscles in order to build muscle. While cardio may burn more calories during a workout, strength training in itself results in a metabolic spike after a workout, this means that calories are burned even after the workout.

Answer 2

One of the main difference between cardiovascular endurance (training) and Strength Training is Cardio challenges the pumping and amount of blood that is constantly being supply to your muscle, while strength training challenges your muscle capacity to lift an object (weight). You can refer Cardio as heart or the Circulatory System and Strength for muscles.
