Gym vs swimming pool

i would say that swimming is an over all work out. swimming works out the whole body. i would say do both this way you brake up the work out and you won't get bored. once you are bored then you don't want to work out. so do both and enjoy

Personally, if those are your only two options I'd go with the gym. I tried swimming all last summer, nearly every day of the week. But I didn't lose a single pound! I didn't even look like I was in shape.

Now that I'm running this summer, I still haven't lost any weight. But at least my legs look all nice and toned. Well, they're getting there.

If you want to lose weight don't start weight lifting. Weight lifting will definitely put weight on. It will tone up your muscles and make you fit, but it will build muscle. I don't recommend it for weight loss.
If you know how to swim just go out and swim a few laps. Professional athletes may have a way of making it look easy, but just several laps of the pool and be very exhausting. If you can do that and still want to do more, go ahead. But if you do too much you're going to feel sore and burnt out. Take it a little at a time. You can always do more next time.
After you have worked out for a while and you are in better shape, you might want to consider weight training. It might be a nice break from all that water. It's messy and requires a lot of clean up. It can dry out your skin and strip your hair its healthy color and shine. In time, weight training could strike a nice balance between the two. You could even have the convenience of having some equipment at home, so you can do it while watching a ball game and save time and money.
It can grow tiresome doing the same thing all the time. Some variety can add some spice and convenience. In the end, as long as you do a workout, you may have something in your daily routine that you look forward to and keeps you feeling up and motivated. It may make you eat better food and eat more healthy food.
When you feel better, people can tell, your attitude can really reflect that. You may want to lose weight now, but once the weight is lost, you will want some other motivation to keep your interest. A workout can be very addicting. You may find you don't want to have to miss it. That's when you know it's no longer about weight loss

I'd also go to the gym, but I'll run a lot and do a lot of cardio. This one will definitely make you lose weight. And then make sure you have a healthy diet. You need to go the gym to lift some weights, not heavy ones. You need weights to make sure that you won't have sagging skin from the weight loss.

After swimming i want to eat more. But after gym i don't have a big appetite. I prefer do regular gym.
