The actress -- who placed fifth on DWTS -- thanked her dance partner Sasha Farber "for helping me shed my insecurities and getting me to the confident and strong place I am today!"
Alyson Hannigan may not have won the Mirrorball trophy on Dancing with the Stars, but it's safe to say the actress' time in the dance competition series impacted her life in more ways than one.
On Saturday, Hannigan -- who, along with her partner, Sasha Farber -- placed fifth on DWTS -- revealed on Instagram that she "lost 20 pounds of weight and emotional baggage" from her time competing on the ABC series.
The How I Met Your Mother alum shared a before and after photo in her post. The first shot was from a DWTS promo shoot taken before the completion began, while the second image was shot during the finale earlier this week.
