I use the gym mat mainly for back exercises, sit in, lie and be done kneeling. In all these exercises you will be well protected against the hard ground by the AIREX mat and has not yet feel that the mat is too soft. I can only recommend the gym mat AIREX for physiotherapy exercises. This exercise mats could readily be used in a professional gym. Also convenient is that AIREX a wide rubber band for keeping the mat mitschickt, with which you can roll up and tuck the mat easily. The only downer is that the mat takes some time until it is no longer this new odor "has. But that is more of a general problem of all gymnastic mats and is therefore no reason for me to mitigate the vote. Therefore, full 5 stars !!!
