Jade and Cora interval training

The expected knock tells you that your first pair of students has arrived and you decide to let them in yourself. Opening the door, you find that rather than standing motionless beside the entrance, both girls are performing static stretches, as if in the final stages of cooling down after vigorous exercise, although they immediately stand up straight on their extraordinary wedge-heeled training shoes to greet you with a smile and a wave.

"Late finishing your training session?" you ask the glowing twenty year olds.

"Oh, no, Professor," the fit redhead Jade answers, "we're just keeping ourselves supple so that we can start our next ones right after the tutorial. With the match next week, I for one need every bit of training I can get."

Even if you hadn't read the information during your preparations earlier, the distinctive reverse J-shaped bruises adorning her fit thighs beneath the hem of her pleated crimson skirt would have let you guess she was a hockey player.

"The same here, Professor." Curvaceous Cora's sport is less easy to discern, the muscles visible in her arms perhaps suggesting weightlifting, but you know that she has half-blues in both taikwondo and volleyball, an unusual combination to be sure, but one that seems to be working for her.

"Well, I wouldn't want to be responsible for the college losing a vital play off—"

Both girls laugh when you say this as though you made a joke and you smile back at them, because it's nice that they think you have a sense of humour, even if you don't actually know what was so funny.

"—so if you'd like to continue exercising during the tutorial, I'm quite happy to accommodate that, as long as it doesn't distract you from your academic responsibilities."

The girls glance over to one another in surprise, then confirm that they'd find that a very helpful use of their time. Accordingly, you commence one of the strangest lessons you've ever taught, with two irrepressibly cheerful young ladies discussing their essays and exploring the source material whilst alternating between press-ups, squat thrusts, star jumps and skipping, using ropes they apparently carry in their backpacks at all times for just such an occasion.
