Cardio equipment "it is one of the most important parts of your workout. before strength exercises, you need to warm up and you use cardio equipment for this. As the final stage of the workout, you again use cardio. Also, sometimes I do only cardio, without strength exercises, because cardio increases the overall endurance of the body, improves blood circulation, strengthens the heart muscle and, of course, burns fat. So I recommend everyone to use cardio in their training programs."
