aerobic exercise

Many people who aspire to build muscle wonder, "Does cardio kill muscle gains?" This is an understandable question, as no one wants their hard-earned sweat equity in the gym to go to waste! 

Many people are probably like myself when it comes to working out. For example, my personal goal is to find the most efficient workout that can be done in minimal time that elicits maximal results.

Many younger people engage in strength training for reasons of vanity rather than possible health benefits.

High intensity interval training (HIIT) has many benefits. The big one being HIIT burns more calories in half the amount of time as traditional steady state exercise.
