Do people really believe these claims? I guess they do considering the number of repins that this one has. <sigh> To show that this does not work in seven days, I am doing this one for 7 days. I will be doing increasing reps starting at 8 with 3 sets for each exercise.
Here is the first one. I will update it in 7 days to show that no, in 7 days your arms will not suddenly look like a young goddess! Enjoy, I did making it and I laugh at myself all the time.
