Aerobics/Aerobics Step


I am no longer able to run for any distance because of my knees that are both arthritic, and the fact I am overweight by about fifty pounds. I still like the 'action' of running, even if its at home on a treadmill while watching soccer on tv. Stationary bikes and ellipticals just dont do it foe me. I was thinking of getting an aerobic step. Would that be sililar to running without the impact? Would it burn as many calories? Thanks!

Hi Bud thanks for the question.  I'm glad to hear that you are working out consistently!  A step could actually be pretty hard on the knees unfortunately.  I think it may be ok every now and then but I wouldn't recommend it as a primary form of exercise if you already have arthritic knees.  Stair climbing (similar motion to a step) places quite a bit of stress on the knee joint which could be balanced with frequent stretching/strengthening exercises but most people don't do enough of that so the knees take the hit.  As for the calorie question, it could burn a lot of calories if the intensity is fast enough and you are doing it for a stretch of time (perhaps 20 min with intervals).

I hope that helps!  Thanks for the question!
