No question in my mind, R C's attitude and appearance, makes her a proper Lady through and though.
N.B. Bossman does not use breeding and monied backgrounds, to judge what constitutes a Lady. Wearing Gucci or Prada does not make females immune to being rude or bitchy.
As long as you have a nice personable personality, you could wear comfortable charity shop clothes, and that would satisfy Bossmans criteria

Presumably with Curl Ups, you mean Bicep Curls, not those Hamstring Curls done lying down on a Machine.
As for T E's, they can be a bit of nuicance if you can't get the Arm up dead straight when weighted. I always favoured an Arm motion where the Forearm moved down the back, not across behind the Neck, becasue you might have to force the Arm past 180 degrees,to get the Dumbbell past the Neck, or tip the Neck forward, displacing the Cervical Vertebrae a bit, which might not be ideal, if you are putting a bit of stress on or around the area.
Then if you sit down to do them, use an inclinded bench. In the past when I did them, I occasionally used a flat one, and once or twice, nearly tippled backwards

I'd be tempted to say 10 rep sets on those, not 15's, that's just underworking a little. Most novices wouldn't do 15's. Yes, very light to start, but around 8-10 reps. 15 will just promote more Lactic Acid.
I'd even be tempted to Switch Bicep Curls for E-Z bar and possibly Extensions for either Skullcrushers or Pressdowns.
That's just me though.
