To state a claim for unconstitutional conditions of confinement, a plaintiff must allege that a defendant's acts or omissions have deprived the inmate of "the minimal civilized measure of life's necessities" and that the defendant acted with deliberate indifference to an excessive risk to inmate health or safety.

"An Eighth Amendment claim that a prison official has deprived inmates of humane conditions of confinement must meet two requirements, one objective and the other subjective."

Plaintiff need not show that he would have been successful on the merits of his claims, but only that they were not frivolous.

"Under the objective requirement, the prison official's acts or omissions must deprive an inmate of the minimal civilized measure of life's necessities. The subjective requirement, relating to the defendant's state of mind, requires deliberate indifference."

—only forty-five minutes of outdoor exercise per week for six weeks meets objective Eighth Amendment requirement

—plaintiff must allege that he "could not present a claim to the courts because of the state's failure to fulfill its constitutional obligations

A prohibition on outdoor exercise of six weeks is a "sufficiently serious" deprivation to support an Eighth Amendment claim.
