You're right SKYWATCHER, SparkPeople isn't the best place to get medical/exercise advise and I appreciate your advise. I do plan on consulting my physician about whether my bulging disc has become a herniated disc this week (possibly due to some oblique ab exercises). Something definitely happened this week. I just thought I'd get some ideas from others and then when I see my doctor I'd be able to ask specific questions about any specific exercise and whether I should or shouldn't do that one.
I wasn't told not to do any exercises, when they told me about the bulging disc 1-1/2 years ago, but I definitely tamed my workouts down and I feel like my body is now showing me the signs of it with weight gain and week ab muscles.
Thanks again for your advise and concern.
