What are some strenuous activities that require a lot of fast movement?

Wind sprints!

The first thing I think of is high-intensity interval training.

Oh! You mean upper torso related fast?? Dodge ball!

Dodging legitimate questions from the press if you are Donald Trump.

Figure skating

Running marathons

Ballet

Softball

Tennis

Volleyball

Gymnastics

Loving the wind sprints, totally may use that one. Any ideas that aren’t sports/exercise related?

Running up the stairs in a coliseum to the “400” section.

martial arts speed training
jumping jacks
trampoline

Fencing.

Pole dancing

I’d go with trampoline.

Or go all the way and go “unless you’re bronco/bull riding”.

Fighting off an attacker.
Escaping across the rooftops.
Fleeing an erupting volcano.
Battling an angry gorilla.
Defending the earth against invading aliens.
Keeping up with a two-year-old.

But…seriously, I would want a bra that has my front.

I have a mental image of someone in one of those human flight suits, and when she lands, her bra is around her neck.
And, @Jeruba, me too.
