It seems nowadays everyone who likes to train with weights hates doing cardiovascular exercise. With this has come an emergence of creative forms of resistance training and interval training that more closely resemble the weights we love and the cardio machines many of us hate. We discuss a research study looking at just how many calories weight training burns and discuss pros and cons of doing more weights, less cardio, or keeping some more traditional cardio in our training split.
