Lack of mindfulness during effort

[huan_mario]

Hello

When I'm doing any physical activity that requires some physical effort - workout, changing tires or just carrying things - I get extremely involved in my thoughts. I just can't get out of my head. I try to focus on breath but the focus is very shallow and I almost immediatly get in my head again. This is very bad for me, because these are often some negative scenarios, judgments of myself, etc. It makes me feel really bad and frustrated afterwards. I'm doing mindfulness meditation for quite some time now.

Does anybody else experience something simmilar? I couldn't find any topic about it
