Is it possible to get a good cardio workout without doing cardiovascular exercises? It appears that bodybuilders from 60s to 80's rarely relied on cardio to get in shape. They just decreased the rest between sets to get into shape. I assume the decreased rest between sets burned calories by giving them a good cardio workout. In essence, the cardio was built into the workouts. Do any getbiggers utilize this principle?
"The use of cardio exercise to get into shape was surprisingly nearly non-existent in the time period from the 1960’s to the 1980’s. As mentioned before, gyms were well equipped with barbells, dumbbells and heavy, basic machines. Cardiovascular equipment such as treadmills, stair masters and elliptical machines were not developed yet. Some gyms would have a couple stationary bikes included in the establishment but they were not nearly as comfortable or as advanced as the equipment that frequents health clubs today.
Bodybuilders got into shape for competitions by both adjusting their diets and increasing the intensity of the workout.The intensity of a workout was often adjusted by decreasing the amount of rest taken between sets. By training faster, bodybuilders would automatically train harder. Arnold was rumored to train with so many sets and so quickly that he would need three sets of training partners that he would alternate with workouts in order to keep up with him. With the decreased rest periods between sets and the increased volume of the workout, bodybuilders could get into top contest condition without the use of cardio."
