I exploit this by making the dynamic stretch a “gateway” to jelqing work.
By dynamic stretches you mean Jai stretches? I have tried them when i was a newbie but not for so long and i dont know if they were effective because i was gaining anyway in that time.
Some people gets nice results from Jai stretches and thats fine but i dont recommend them. Thats because its not the force you apply that will lengthen the penis but the time under stretch. Although someone can gain with short duration stretches done at high frequency, but my opinion is that one stretch should last at least 60 seconds.
Big al’s side to side stretch seems like simple stretching to me. The side to side movement is unnecessary and you are right that it can cause an erection. There is no reason to move your penis during the stretch, if you want to target different spots fulcrum stretching is the answer.
As a general rule remember to relax into the stretch and go for longer holds. We try to enlongate a living tissue not a material. Start the stretch with low force and progressively and smoothly increase the force. Then stay at that length and relax.
rate of loading and deformation
When connective tissue is loaded at faster reate, it deform less than when the same tissue is loaded at a slower rate. Furthermore, the CT structure will have a higher ultimate strength (ie, the highest load applied
before failure).
