Today i'm making my little sister workout with a professional bodybuilder. Claudia is 100lb and loves to workout at the gym but she wants to gain weight and muscle. I found the biggest dude in our town to be her coach. Will she survive the intense bodybuilding training? Claudia's final fitness transformation will be in the next episode.Watch the last episode "WHO'S THE FAVORITE SIBLING":https://www.youtube.com/watch?v=vYYpXH3cRa8Big Thanks to Austin for being an incredible trainer and bodybuilder:https://www.instagram.com/austinl_simpson/Thanks to Anarchy Gym for letting us use their gym:https://www.anarchygym.com/Claudia's Instagram:https://www.instagram.com/cllaaaudiaaSUBSCRIBE FOR NEW WALSH FAMILY EPISODES:http://bit.ly/Subscribe2WalshADD ME ON INSTAGRAM: @brandonwalshhttps://instagram.com/brandonwalsh I’m a 24 year old dude creating a reality show about my crazy family:https://youtube.com/brandonwalshofficialFollow The Walsh Family:Kennedy(sister): @kennedyclairewalshClaudia(sister): @cllaaaudiaaJen(mom): @jenthebodypainterCory(editor): @corywolbergDevorah(friend): @devorahroloffPapa Walsh(dad): @papawalsh7
