Swimming

Thanks, that's really helpful - I'm going to buy a pull buoy and try exclusively with that to get swimming fitness/technique better (I'm starting from a pretty low base here!) and then try to work out how to swim without it!

The pull has one side bigger than the other, so basically the bigger side down in the water will be more floaty, the smaller side less floaty.

I use the less, because im a girl and I have a more floaty hip area anyway.
Try both sides and see which you prefer.
It goes in between your thighs, right at the top/crotch. Lower and it can cause back pain.

Have a go. It is weird to start with but just focus on the roll of the hips.
