I would love to be able to swim confidently. I didn't learn to swim properly until I was 18/19 years old as I just wasn't confident in water, before that I could doggy paddle and float about but not do lengths.
I would love to be able to swim daily for exercise, but after one length my body aches. my arms hurt and I'm breathless and my neck is stiff and sore. I'm not unfit, I run daily, play group sports, just can't seem to swim for 'gentle' exercise. I'm not overweight. Where am I going wrong and how can I get better?
