I have lost about 15 pounds so far on my weight loss quest and have been doing my HIIT running for 2 months. I have a few more pounds to lose until the ab muscles really come out. I have been playing sports my whole life and now with this cardio that I do every couple days makes me realize that I have been running my ass of for the last 17 years of my life and I am starting to get sick of it. I know that people have said that they have lost great weight by doing swimming instead of running as their cardio. I dont quite understand how this is possible. I mean I dont feel like swimming for 30 minutes is even close to running for 30 minutes as heart rate and amount of calories are burned. Can some1 give me an opinon on the pros and cons of switching from running to swimming. Will I be able to shed these last 5-10 pounds by doing so. Thanks.
