I have been able to complete 5x36. Last set is a struggle, but form is maintained. However, when I attempted to move on to 4x48, I could get the first, the second with great effort, but nowhere close on Sets 3 and 4.
I am trying to decide whether or not to use steady state on 36 seconds, or whether I should try a smaller interval of increase, such as 4X38 seconds.
Any thoughts?
