Place the following code at your listing page

<?php $catquery = new WP_Query( 'post_type=article&posts_per_page=4&article-visibility=fitness' );
while($catquery->have_posts()) : $catquery->the_post();
?>

   <article class="post home-post">
       <a href="https://wordpress.stackexchange.com/questions/222979/<?php the_permalink(); ?>">
           <div class="post-thumbnail-img">
               <?php the_post_thumbnail('small-thumbnail'); ?>
           </div>
           <h2><?php the_title(); ?></h2>
       </a>
       <p class="post-info">
           <?php the_time('F jS, Y'); ?> |
           <?php get_template_part('block-athlete-archive'); ?>
        </p>

       <p>
           <?php echo get_the_excerpt(); ?>
           <span class="readmore">
               <br><a href="https://wordpress.stackexchange.com/questions/222979/<?php the_permalink(); ?>">Read more &raquo;</a>
           </span>
       </p>

   </article>

<?php endwhile; ?>`

<div class="pagination">
            <?php kriesi_pagination($catquery->max_num_pages); ?>
</div>

After complete the above process you must update your permalink.
