You should be doing at least 30 minutes of cardio 5 days a week (getting your heart rate into the "target zone", not the "fat-burning zone", as that myth has since been debunked), plus weight training at least 3 days a week. Your food intake is about 80% of the battle, which is important to think about. You might want to consider keeping a food log and actually measuring your food to see what you really take in. I'm on my own weight loss journey, and I've lost 58 lbs so far running 3 days a week, biking 2, and doing strength training 3-4 days a week. Feel free to PM me if you like, if you want to know what's worked for me (not selling anything!). Good luck!
