My work out consist of 15 mins on a stationary bike and 40 mins on a X-trainer. This time seems perfect for me and I am having a good time with it... I do this 5 days a week and then after this work out I do weights. I don't spend much time here but enough to "feel it burn a bit" So far it seems I loose more inches faster by doing both intead of just one..... Expleshy in the major areas...
Good luck !!
