Justin Timberlake burns Thanksgiving calories doing push-ups with son Silas

The singer took to Instagram to post a very adorable video of himself doing push ups with his son Silas on his back to work off those mashed potatoes. "Shaking off those leftovers like... Hope everyone had a great Thanksgiving!" he captioned the video.

In the video, Justin was wearing a black shirt, shorts and white marbled leggings while using his little one as extra weight for his exercise.

Silas lied flat upon his father's back donning sweet red shorts and a white tee.

The shadow of mom Jessica Biel could be seen, as the star helped film the father/son fitness moment.

The NSYNC standout counted out six reps before the end of the short clip. The day earlier the SexyBack singer didn't seem to be worries about a little extra holiday stuffing.

His wife of five years shared a glimpse of Justin's domestic side on Instagram, posting video of the Cry Me A River singer preparing a fantastic meringue pie.
