Dans la phrase "Pilates is as ystem of exercise that focuses on developing core strength and balance throughout the body", comment traduiseriez vous "core strengh". "developper "votre force interne et l'equilibre a travers votre corps" peut etre??
I think that the answer has already been given here

They suggest "muscles de soutien" for core strength
I would avoid "force interne", because it means more psychological strength,
the strength of your mind, will, etc
A bit late to the party, but "muscles de soutien" seems suspect to me. Do people really say that? A friend just mentioned gainage, which I think might be the solution.
