ADS is just a tool. Some of the ADS device produce the same amount of tension as hanging with moderate weights.
ADS is hands free for the most part, so those of us who use them appreciate we can watch TV and for the most part “relax” while using them.
I think most people involved in serious PE will evaluate all the available tools, and have some at their disposal.
Many of you imagine spending $100 or $200 as a waste for a PE device. I did too, at first with some scepticism. However the devices work, and save me time and energy. I think I did well.
I personally use a Static Stretcher, I got the full kit for $249.
I also have a Boston Pump, using a McMaster brake bleeder vacuum pump on it. I personally can see paying $200 for a variable cycling-electric vacuum pump too!
I also personally do Jelq’s, usually before or after applying one of the PE tools I have and various manual stretching methods.
