Wrap every 2 posts with a row-fluid

I’m trying to wrap every 2 posts with a class of “row-fluid”… html example below…

<div class="row-fluid">
    <div class="post 1"></div>
     <div class="post 2"></div>
</div>
<div class="row-fluid">
    <div class="post 1"></div>
     <div class="post 2"></div>
</div>

Right now I have the following html output

<div class="row-fluid">
    <div class="post 1"></div>
     <div class="post 2"></div>
     <div class="post 3"></div>
     <div class="post 4"></div>
</div>

I’d like to set a count loop if its at all possible to achieve wrapper every two posts so I can use twitter bootstrap properly without having to tweak the css and over-ride what bootstrap already has.

<?php

					$args = array( 'post_type' => 'mysite_team', 'posts_per_page' => 10 );
					$loop = new WP_Query( $args );
					while ( $loop->have_posts() ) : $loop->the_post();

						echo '<div ';
							$even_odd = (++$j % 2 == 0) ? 'featured-image-wrapper-even-post span6' : 'featured-image-wrapper-odd-post span6'; post_class( $even_odd );
						echo '>';

						echo '<h1>';
						echo '<a href="';
							the_permalink();
						echo '">';
							the_title();
						echo '</a></h1>';

						echo '<div class="featured-image alignleft">';
						echo '<a href="';
							the_permalink();
						echo '">';
							the_post_thumbnail('team-thumbnail-size');
						echo '</a>';
						echo '</div>';

						echo '<div class="entry-content">';
							the_excerpt();
						echo '<p><a href="';
							the_permalink();
						echo '"><i>Read More';
						echo '</i></a></p>';
						echo '</div>';

						echo '</div>';

					endwhile;

					?>

Any help would be awesome as I have tried a few things but keep getting white pages and no errors to go off of.

Thanks in advance!
