The dataset includes the following exercises:
<ol>
<li>Bicep curls (alternating)</li>
<li>Pushups</li>
<li>Sumo squats </li>
</ol>

Each video is accompanied by a rich set of pixel-perfect labels and annotations. Highlights for this dataset:
<ul>
<li>Mean brightness of entire 2D image</li>
<li>Mean brightness of avatar pixels</li>
<li>Mean brightness of local region surrounding the avatar</li>
<li>Brightness contrast between avatar and local surroundings</li>
<li>Color contrast between avatar and local surroundings</li>
<li>Color contrast between avatar and local surroundings.</li>
<li>Mean signal to noise ratio of entire 2D image</li>
<li>All the usual labels including rep counts, avatar characteristics, camera location, 2D/3D kyepoints, etc. </li>
<li>And much more!</li>
