I’ve heard quite a bit now about coaches who get people into “metabolic” phases for “x” amount of to almost prime the body to then either grow or lose bodyfat.
They use this to only do a load of metabolic aerobic work with supersets and high volume to improve aerobic capacity to utilise carbs better etc and be in a better place for the next phase.
I don’t think this is something that you do, could you explain the theory behind this and how you go about it instead?
I personally think it serves no purpose. And in the past when I’ve messed around with implementing them, pretty much everyone (minus very “enhanced” individuals) lose a significant amount of tissue.
I personally think the best way to improve insulin sensitivity, is to recover. Reduce inflammation, acidity and improve sleep. That’s why I do like “recovery phases” how I do them. You won’t lose tissue with the loads you use. But the drastically decreased volume will do everything mentioned above. And as I outline in my recovery phases, it’s a great opportunity to go into a deficit, drop some body fat, and work on aerobic capacity (from direct metabolic work). So it accomplishes everything, and you get to keep your muscle.
