4D OVERWEIGHT CHANNEL

Hello All! I am curious to know if anyone else has checked out this YouTube channel and, if so, what's your opinion on the effectiveness of the workouts. I really like that they use a larger-sized female animation and most of the exercises are easy to do except, for me, the floor exercises. Although I am committed to exercising every day, I don't want to waste any effort on activities that just aren't effective. I am particularly working on arm strength and reducing flabby upper arms. I would welcome any info you're comfortable sharing. Thank you so much!
