Very Sore After Gymnastics Class? I am a competative cheerleader for my high school and I used to have practice everyday with very intense practices. The season ended about 3 months ago and I haven t really done anything intense within that time period. Yesterday I had a tumbling class (which is basically gymnastics if you don t know) and I hadn t really done anything for a while. We didn t stretch before this practice like you are supposed to and we jumped right into standing back flips without stopping in a row. I threw my head/neck back every time and you are not supposed to do that. I only did it because I wasn t properly warmed up. After that we did a lot of extreme tumbling skills such as multiple flips in a row including skills that do not require hands. Now today I feel really sore, which is normal, but I noticed that my chest hurts a lot and I keep getting a little light headed and shortness of breath. Do you think that I could have pulled a muscle or something more serious? I usually do not have this problem. Thank you!
