How much porridge should you eat?
Last week we talked about eating your porridge — finding the right dose of exercise rather than blindly doing 3 sets of 10.
This is where RPE — Rating of Perceived Exertion — comes in.
In strength training, RPE helps account for the fact that your capacity changes from day to day.
Some days you’ve slept brilliantly and feel on top of the world.
Some days you’ve barely slept, you’re stressed, sore and running on fumes.
So why would exactly the same number of repetitions always be the right dose?
The problem in rehab is that most people don’t really know what a true 10/10 effort feels like, and when we’re working around pain, maximal effort usually isn’t the goal anyway.
So we keep it simpler.
Did you do enough that you could actually feel it?
Did you stop before you completely overcooked it?
Good.
More than not enough. Less than too much.
Eat your porridge :)
