I've been exercising pretty consistently for several years. I've really been dedicated to conditioning work that is either working with weights or doing Winsor pilates. What I've learned this time around is how much the conditioning has helped me to avoid injuries when doing other kinds of exercise.
I too had trouble with my lower back because I had no ab or upper body muscles. When I first got my Winsor pilates for abs, I tried it and gave up after only a few moves. Now I can do them all except for the neck pulls where you roll up with your hands behind your head. But I'm getting lift off from the floor!
So what is my point? I guess its the importance of conditioning because by really focusing on building muscles it makes doing the cardio easier. With a good muscle base, you have more control of your body.
Hope that makes sense!
I recently went to a gym with my sister. I tried a recumbant bike and hated it. All because of where I carry the weight - mostly in my lower abdomen area. It felt like I was kicking myself in the gut every time my legs moved. I also had difficulty with several of the machines because of it too. I moved on to machines that didn't feel awkward.
When I first started walking over 10 years ago, I could walk down the block and back. I kept at it until I could walk around the block. It was such a good feeling that I could do it. I worked up until I was able to do 10K walks. I did a lot of 10k walks over several years of participating in Volkswalking. Then I decided to get brave and buy a bicycle. I'd only ride it at night at first just in case someone might see me. I decided that I loved riding more than walking. At 250, I decided to train for the MS 150 where we were to ride 60-100 miles the first day and then 50 the next. I trained by starting out riding two miles loops at a nearby park. That first loop around was so tiring but so satisfying too. By September, I was riding 40-60 miles on the weekend. When I made the 100 mile ride on that first day, I came in 8 hours after starting and tears rolling down my face. I weighed approximately 228. It was such a victorious feeling. My motto is, don't ever give up; start over but don't ever quit.
