You haven't earned the right to "go hard or go home"

I've come to believe that as motivational as that may sound, most individuals haven't earned the right to be "worked out."

"Can you make it hard today?"

What's the optimal environment that would support that request?

Plenty of sleep--consistently.  Insulin is stable, hormones aren't flippin' around like fish on the pier.  Eating high quality, clean, nutrient dense food.  Life is not too stressful.  AND...
you have lots of experience training in that cellular environment.

So...'can you make it hard today?'

No.  Not for you.  Not today.  You have bags under your eyes.  You're anxious, you're checking your phone in a class you paid for.  If I stress you today, your body will perform this equation:

Preexisting Stress + Exercise Stress = Shut down

Your body cannot differentiate between stresses.  It cannot understand that your relational stress is different from your work stress, and that is a different stress from whatever it is you're calling your Elite-Endurance-Shred-Cardio-Sculpt-Sizzle class.

So...'can you make it hard today?'

Sure.  Go home, get 7+ hours of sleep tonight.  When I see you next week, tell me all the reasons you were unable to do that one simple thing.
