I'm just wondering if a stepper (stair master) is considered a cardio or more for building muscle and toning, like lifting weights or rowing etc..
If your heartrate goes up, its cardio.
really?? I lift heavy and my heart rate goes up, so that is cardio?
Ouch that was a nasty reply.
Technically, cardio - short for cardiovascular, applies to both. Aerobic/anaerobic would differentiate the two.
I would consider it anaerobic.
Its both. Primarily, its a cardio workout, but it can contribute to developing your leg muscles. If you stand up straight, it will also workout your core.
I used to do the stairmaster every morning. I also turned it into a great isometric exercise for my triceps as I'd support myself the entire time.
it's not anaerobic if you can do it for longer than a couple seconds at a time.
it is an aerobic activity if you are doing it at a steady pace for an extended period of time.. however, if you increase the speed or resistance to a point where you can do no more than about 30 seconds at a time, it becomes anaerobic.
because you are human you cannot sustain an anaerobic activity for an extended period of time or you will die (anaerobic means "without oxygen", if there's no oxygen supplied to the tissues the cells will die)
aerobic activity means "with oxygen", these include activities which you can do for an extended period of time (walking, jogging, biking..etc)
most exercises use both the aerobic and anaerobic metabolisms, however the ratio differ depending on the activity.
The stair stepper may help to build muscle to an extent, but it does not replace regular weight training... consider it being cardio
