Ok so I have a few questions. I have been working out pretty religiously with my sister 3-4 times a week. Mostly we use the treadmill at the gym, I do realize I need to change it up. But, I have a hard time with the stairclimber, I feel as though I'm just not in good enough shape to stay on it long enough to burn as many calories as I can on the treadmill. Same thing with the elliptical. These are my questions I hope someone out there can help me with. When I use the treadmill I enter my weight and check my heartrate often. How accurate are the Lifefitness treadmills at calculating calories burned? Should I really keep my HR in the 65-75% max HR range for fat loss? Is it better to go faster with low incline or slower with high incline? Whats the difference? How bad is it to hold on, I always feel like I'm gonna fall off or fall over sideways? Should I eat before I go to the gym? After? What? I'm working really hard for me right now at pushing this weight off but I don't want to bulk up to much yet. Tonight I walked at a 3.5 speed with incline intervals in twos every 3 minutes up to 12 then down and up for 50 minutes. Treadmill says I burned 600 calories and walked about 3 miles after cooldown. Is that good does it seem right. Should I use less incline and more speed to burn fat.
I know theres a bunch of questions but I really want to know if I'm on the right path to skinny. Thanks everyone.
