Sorry to hijack.
I'm looking to join my local gym to take full advantage of their swimming pool, I'm obese and probably at the heaviest i've ever been, I've never been fit in my entire life, but I've always been a confident strong swimmer due to having swimming lessons for a good number of years when I was younger.
I've gotten to a point where i struggle to go on a simple walk where after 5 mins I start to get pain in my back which i'm quite ashamed of that i've gotten myself to that stage where I can't even take a simple walk to town or whatever with my mates without struggling with pain and drenched in sweat.
I know swimming is a low impact exercise but very effective for weightloss and muscle growth (Especially for someone who barely uses their muscles) since you're using all your muscles to get you going, What's the most effective swimming technique? I've always thought breast stroke was the more intensive exercise in the pool.
Cheers.
