I have noticed that one area of the 30-10-30 protocol that appears to have caused some confusion is when the 10 rep portion of the protocol finishes and the 2nd 30 second negative begins.
It seems that some people believe you should reach failure prior to commencing the negative, whereas others see that the focus is on the negative and that getting as close to (especially for someone without a training partner) failure as possible , but completing the last rep, so as the negative can begin immediately is the better way to apply this technique.
My own views sit strongly in the second camp, although someone with a training partner may on occasion get their (slight) assistance to complete the last positive repetition.
For someone training on their own, the problem with reaching positive failure is that there will have to be a significant time delay before the weight can be raised to the top and the 2nd negative attempted .
Such a method may have it’s merits, but to me it is not 30-10-30
I would appreciate your thoughts Dr. Darden.
