Ok well I just signed up for a year membership at my gym, and I was on the treadmill, I thought I was doing good. My heart rate was up to 170, I was like yes im doing pretty good im losing some body fat. My personal fitness instructor told me to keep my heart rate between 130-160, im 18 years old by the way. He said if I go over 160 im burning fat, and MUSCLE. I dont want to burn muscle lol. But here if the thing, this other personal fitness instructor I had said it doesnt matter what my heart rate goes up too, can somebody please tell me if my heart rate goes up over 80%, am I burning fat and muscle?
And here if my other question, im almost down to the weight I want to be. I am about to start my weight lifting. Is regular crunches a good exercise for your abs? I do crisscross crunches to, where I touch my right elbow on my left knee lol, if that a good exercise for your abs also? And when you work out your abs can you do as many as you wants, or should you do sets of crunches?
