Morning I prefer the sweating kind of exercise too. Have tried yoga but couldn't really manage a whole class as found I got a bit bored tbh. Also made me giggle. Pilates seemed more 'interesting'. After going with a friend though I do Body Balance regularly which is a mixture of Yoga, Pilates and Tai Chi. It's set to music and is more varied (and not spiritual and giggle inducing)so I'd have a look to see if any of your local centres offer it.I do it at the local YMCA where you can pay as you go. Perhaps similar near you?
I see yoga as a practice and have tried pregnancy yoga and agree that it seems like lots of huffing and puffing, and I have a giggle.
It is different from the yoga I used to do, which I sometimes still used to have a real giggle at (i'm no expert and am really inflexible and wondering if I can ever get back to doing yoga post pregnancy.....).
I have been doing Yoga for quite a few years and absolutely love it. I started after dd1 as i wanted to tone up and now do it every day with an hour and a half lesson once a week.
If you do it properly it is actually very strenuous and you really feel like you have had a good work out afterwards.
My Mum has been doing it since she was a child as she uses it to help control her asthma. It can teach you to control your breathing and some people believe improve your lung capacity. I just do it because it makes me feel good.
I started using an earlier version of Barbara Curries DVD this one. I think its fairly good, but I would recommend going to a good yoga class as well.
