When my doc told me that working out wouldn't hur my back more, I started exercising again. But I had been doing absolutely nothing for about five weeks before that and it is hard to get back on track. I went jogging for half an hour every day before my backpain hit. Now, after two weeks of building up, I can do 20 minutes and I am absolutely dead afterwards.
I've also changed my morning yoga into a more challenging posture muscles exercise program that is going well. That means, I can see a lot of difference after those two weeks. I still have very weak back and ab muscles and trying to keep myself upright during the day often gives me back pain. But I think I'm on the right track.
I started an interval training program two days ago to see if that can boost my endurance platforming. Today is day two, it's sunny and I'm looking forward to hit the track. Wish me luck! ;o)
P.S: Posting is not so frequent since I'm staying with my family until Monday and I want to enjoy the time with them. It's a weird thought that I won't be with them for Christmas. It will be the first time in my life and it is a bit scary.
