An exercise apparatus, comprising a support structure; a platform mounted on the support structure to support a user's legs, and to allow pivoting of the user's trunk about a generally horizontal axis as the user relatively bends his body and his legs; and other structure associated with the platform to induce contraction of the user's thighs relatively toward one another in response to the trunk pivoting, for producing anterior rotation of the user's ilium, thereby inducing distraction of the user's sacroiliac joint, at the ilium posterior; the other means including a thigh grippable element projecting into an inter-thigh region of the user's legs, to be clamped between the user's thighs.
