Coq,
Good to have you here man! Welcome to the gym.
Your routine sounds intense. You tie the base with a rope belt eh? Thats a type of clamping method. What part of central america are you from?
The reason I ask is if posssible, you might want to try cable clamps. A description of cable clamps is in
our clamping guide.
Yes, this type of PE definitely helps out with girth. In fact, it is probably the best girth exercise known. The clamping guide has a lot of good information about clamping.
Also, you've been doing PE for nearly 4 years? That's awsome. Do you know your before and after stats?
