I had the most amazing swim last night. It's been years since I swam regularly, but fortunately my endurance came back early on, and now I'm starting to get my speed back, too. I had a stretch of laps in the middle where I swear I was flying through the water (despite my rather non-hydrodynamic shape!) It felt so good.
lifeguard, I am with you. I feel very fortunate that my DH is very supportive of my need to exercise. Swimming is my favourite activity right now by far, and the lap swimming time at our neighbourhood pool is very inconveniently coincident with dinner clean-up and bedtime routine (7-8 p.m.) but DH still encourages me to go as often as I like. I go every second night, and swim laps for an hour. It's so, so awesome. I'm sure part of the reason he is so wonderful about it is that I am a total cranky witch on the days I don't get any decent exercise whereas I come home from swimming floating on air.
Leiahs, I am starting to think about post-baby workouts as well. I expect to be walking daily (DS' school is about a mile away and I'll be picking him up this year rather than using after-care) but that won't be that much activity. I might take longer routes to get there so that I can get a good little hike in.
There are mom & baby exercise classes around me that I took when I was on mat leave with DS. I went in all cocky, thinking hey, I'm a former nationals level athlete, how hard can this be ... ^$&* those classes kicked my behind. They were fast-paced, hard, plus you use the baby as a weight and the kid just keeps getting heavier all the time! However, they were also quite expensive, it was a pain to get to them on time, and DS did not take to them well at all, so I'm not sure if I will do them again.
I've found that swimming and workout videos have really been great for me during pregnancy, so I might just keep up with those. The swimming will require getting the baby taking a bottle, but that's the plan, anyway. And videos are so convenient.
Over the course of a couple of years, I had an injury, followed by another injury, followed by a pregnancy. I stopped playing sports, gained quite a bit of weight through those years and was dealing with something similar in terms of body image. I was starting my 30s, not wanting to feel so out of shape for the rest of my life (and I definitely notice that it gets harder to spring back into shape as I get older.) It took a year or two to make it all the way to where I was happy, but along the way, I resolved a lot of issues and even managed to accept that my genetics are what they are and I am never going to be really thin unless I am willing to make it my top priority in life, and maybe not even then. So weight management turned out not to be a great long-term motivator for me (also, I find that calorie restriction is way more effective for that than exercise), and even health is such a distal outcome that it works when I am close to being motivated, but it won't get me out of a rut. But they did get me started. Now, the immediate gratification of feeling good when I exercise has become really important in my life, so even though it wasn't what got me started, it's definitely what keeps me going.
