You can try something like that (not tested), using a $count variable to store the number of thumbnails so far :

<?php 
$count = 0;
foreach($products as $product) : 

    // open a new row
    if (!$count%4)
        echo '<div class="row">
            <div class="col-md-3 col-lg-3">'
?>
<a href="#" class="thumbnail">
    XXXX
</a>
<?php
    // close row if there is 4 thumbnails in it
    if ($count%4 == 3)
        echo '</div></div>';

    $count++;
endforeach; 

// close the row at the end if the last one wasn't full
if ($count%4>0)
    echo '</div></div>';
?>
