Dear fellow gymnasts, I have been walking around with pain in the upper part of the lower back for the last couple of weeks. The pain is at its worst when I have been in a bended position while standing for a couple of seconds (picking something up from the ground for example) and then standing straight again, or the day after a heavy training session. Such a training session then also includes doing flips ans bar swings etc. The pain isn't the same every day. Sometimes it feels like it's almost gone, but the day after it can feel quite painful again. My question is if someone can help me out with some exercises that might fix this problem, or if someone has other suggestions on how to get rid of this backache. Thanks in advance, All the best, Bas
