I've been going to several spinning classes per week for a few weeks now and have now started my no carb healthy paleo eating this week. But I e just come back from my hour spin class and I feel exhausted, far more than usual. My face is still bright purple and I feel odd. The spin classes are great and burn approx 900 calories per class. I'd like advice please... Should I do spinning and a low carb diet? Will things improve as I get into it? I'm about 4 stone overweight. I'm apparently healthy according to my doctor, but for how long??? I want to become super healthy and fit for the sake of my 2 little boys who are 4 & 2 years old. Advice, tips and info wanted as I start this hard journey. Thanks x
