If running built muscles, I'd choose to run over lifting weights any day. When you are running you get to take in the scenery and once you hit your steady-state of breathing, you DO NOT feel like you are working out all. For me, it feels like I am barely exerting any effort. I get to take in the fresh air, take in the view of the world, all while listening to any type of music or audio. Compared toweight lifting, you get spent during each session. The rest in between disturbs your steady rhythm, so you are constantly being thwarted out of your flow state. You cannot listen to any chill music. The intensity of the workout demands intense upbeat music for motivation. That being said lifting is still a decent pass time. You get to sculpt your body and feel the dopamine rush in after the training session, but when it comes to running, you get the running high during your run, and you get the serotonin after the session. I know doing cardio has a rep for being hard but that rep is developed through bitch mofos that cannot handle a little discomfort of out of breathness. I def recomend this cope if you are looking for new healthy activities.
fair enough. I keep my ear out for that.
