Planks - how to do

[simonp]

My Physio always tells me planks are one thing I should never do.

Interesting - what's the reasoning?

Not good for people doing endurance sport; over-stresses too many muscles and generates too much lactic acid, was her reasoning, IIRC.

They’re part of the abs & core routine I’ve been doing, but I think she might have a point.

Surely those are relatively short term effects though?

no payback except the seconds ticking down.

Except for the sort of toned physique shown in your profile pic!

@Manotea: great illustrations/ descriptions - thanks! I'm going to give the push up position plank a go!
