You will be given rest time for each exercise. Always go heavy and take the max amount of rest. Taking longer rest allows you to go heavier on the next set! Going heavier is what will bring the results you are looking for. Trust me! I could care less about “calories burned”. Let’s focus on building muscle so that you burn more calories as a whole. Ever wondered why the people in the free weight section are leaner and more toned than the cardio bunny? It’s because they have more muscle, and when you lift heavy, your heart rate stays in the fat burn zone vs cardio where your heart rate stays high for an extended period and you risk burning muscle which will lower metabolism. We do not want that.
