For me, the FaceID has been the most pathetic experience ever. It fails to recognize my face 3/10 times no matter how hard I try to re-register my face. So with inclusion of FaceID on the upcoming iPads, be ready to do a lot of head banging against the giant screen. No need for weight training. The exercise will happen trying to bring the FaceID in range. I say 2 sets of 20 reps each.
