I’m currently using isometrics to break through a squat plateau of mine, inspired by Dan John’s recent article ‘3 simple things that work’.
I’ll load up a weight that I can barely get off the pins right at my sticking point, and then sit there for a quick 5-7 count (roughly 5-10 seconds, I imagine).
Is this an appropriate time under tension? For those that have used it effectively before, how long were your isometric contractions?
