Using bands with bar to perform the Barbell bodybuilding training?

Hi guys! I would like to perform the Barbell Bodybuilding training and I’m wondering to invest in this interesting product:

Any one has tried it already?



I tried with Pakama and it was the only Journey ever I didn’t finish.
It’s far away from using a real barbell, some exercises (Bench Presses, Pull Overs or Barbell Lunges) aren’t really doable and even the manufacturer aren’t able to tell you how to calculate exactly the weight you are simulating using the bands.
To be honest, I would recommend to not use these resistance bands with bar to do the Barbell Training Journey.
