i have a cross trainer and have been using it for my cardio for about a year now. My lifestyle is active, so I only use it a couple of times a week. It has many resistance levels, minutes HR monitor(not that accurate) and programs, ie: Weight loss(Up and down 1-2 increase in resistance thn back down again 1-2) Target Heart Rate zone Intervals(Warm up low resistance building up high resistance, low resistance, then high again. Manual(choose resistance then go out at for how many minutes you choose) Rolling(resistance goes up slowly and decrease slowly) Mountain(Increase resistance to max) Do you think my body has adapted to the excersise, The last few times I've been using it was the first times I did Interval program. I'm a bit overweight, that's why I'm doing this with a healthy diet of course, The diet isn't bring as much weight loss as I thought it would, i suppose i need to excersise more. Could this be a good machine for excersing to keep my body from adapting. Thanks
