I found how i can do this after testing the arrays

if ( $trainer ) {
            $trainer_query=array('relation' => 'OR',);
            foreach ($trainer as $value) {
            $trainer_query[] = [
                'key' => 'trainer',
                'value' => $value,
                'compare' => 'LIKE',
            ];
            }

        }

and use this like that in meta query and this solve my problem

$args['meta_query']=array(
        'relation' => 'AND',
        array($min_lenght_query),
        array($max_lenght_query),
        array($minburn_query),
        array($maxburn_query),
        array($difficulty_query),
        array('relation' => 'OR',$trainer_query),
        array('relation' => 'OR',$focus_query),
        array('relation' => 'OR',$trainingtype_query),
        array('relation' => 'OR',$equipment_query),
    );

I have a problem with combining meta_query "OR' and "AND" relations
