[QUOTE 5391525, member: 9609"]My first 'well meaning' pilates teacher had us doing these, I thought they would be good for core strength and got really good at them, 5 - 10 minutes no problems. Could even get the wife to sit on me.
Then I changed to a pilates teacher who knew her stuff and she stopped me doing them as they would be doing nothing whatsoever for my core strength and very likely making my back problems worse, Her theory being; when you have a really weak core your body cheats and uses the wrong muscles, so I was doing the plank by using legs and tummy muscles, and not using the core at all.
She taught me how to use my core with what I would describe as pointlessly silly little exercises - and she was absolutely spot on with me as she cured the sideways twist I had in my spine.
So by all means do planks, but if she is correct then you may not even be using your core.[/QUOTE]
Interesting!
So, can you suggest some 'silly little exercises' as alternatives?
