roundturnandtwohalfhitches excellent news on the resting heart rate. I haven't checked mine in a long time. It used to be a bit on the low side, like 54, but jumped up to 65-70 when I put on weight with the children and inactivity. 54 was not down to any super efforts on my part, btw, just appears to be the way my body works (always at top of healthy bmi for example!). I'll check that in a bit when I've been sat on my derriere for a bit longer.
AdventuresRUs prescription goggles are something else to add to my list. But at the moment our finances are not healthy (I spent most of last night going through them with a fine toothcomb trying to figure out how we are spending so much!) so they will have to wait. Maybe they can be a Xmas pressie from dp. I have a pair of prescription scuba mask goggles somewhere, but I think they would create a lot of resistance and I'd look like a plonker 
SwimmingKaren arrr, don't tell me that! It's the only exercise that I like doing, other than going for long walks and that ain't happening where I live. It's as flat as a pancake and boring boring boring. I'm not a keen runner, especially since I appear to have developed a bunion (just the one) and my heels are dodgy so that it hurts to get out of bed and start walking around in the morning. I really have been very inactive, so I'm going to stick with it anyway and see what happens. I did a quick google and according to this link this one every 30 minutes of vigorous breast stroke burns 372 calories. This means I must be burning 1,488 calories a week, which has to be doing something?!
BretonStripe I need to watch some of those videos too. No one ever taught me to swim and I'm sure I'm doing it all wrong. I seem to put in a lot of effort to not really go as fast as all the effort warrants.
brizzledrizzle you are an inspiration. I must ask though, was this a 50 meter pool
???
Ladies, I swam 20 lengths (1 km) in 29.55 minutes this morning. I am well chuffed. Almost couldn't haul myself out the pool afterwards and my legs felt like lead. I can do this!!!
