Hi Riddick, good to see your having a go mate, welcome to the forum. I think swimming is a great way to do some steady state cardio, it really is low impact and as its getting warm is a great thing to do. Just remember that to get rid of the fat, you gotta watch the cals mate. Yes its hard to work out exactly how much to eat etc, but with a little practice you will get it. Once you find your calorie maintenance, you can than do a few different things to get the fat melt going. At the moment i find that eating as close to maintenance and doing a bit of walking to get me into a small calorie deficit is getting the fat off. Having said that, I'm not to concerned about it over xmas but I will be in 2012.
Good luck mate.
