I'm so excited to see us getting a group together for this! I really love doing Callanetics, and I love getting to share the fun, too.
Welcome to the Low-Carber Forums, ScotiaGirl! This is a really great place for support on your low carb journey, plus you can try all the stuff that other folks say worked for them.
And, hey, LittleZu, don't sweat it that you couldn't do much your first time. I probably only got a few reps per exercise in when I first started, and I didn't have half the physical stuff you're dealing with. It got better for me, though. Hopefully, you'll start seeing some improvement as you do this. Have you considered using Beginner Callanetics? I can't find a free download, but I don't see the sense of buying before you try it.
I'd probably recommend starting by doing minimal reps for each of the exercises and work your way up as you can. Not that I'm an expert of anything.
But, I figure working out a little has got to be better than not doing it at all, so good for you!
I'll be doing Callanetics tonight with a gimpy knee. I didn't work out last night, because I was achy sick. Today, my body wants me to remember the car accident I had 8 years ago. It hurts just enough for me to complain about, but not enough not to work out. Drats!
